The pseudo-amino acid composition (PseAAC) has been widely used to convert complicated protein sequences with various lengths to fixed length digital feature vectors while keeping considerable sequence-order information. However, so far the only software available to the public is the web-server PseAAC (http://www.csbio.sjtu.edu.cn/bioinf/PseAAC/), which has some limitations in dealing with ...

In an effort to produce ricinoleic acid (12-hydroxy-octadeca-cis-9-enoic acid: C18:1-OH) as a petrochemical replacement in a variety of industrial processes, we introduced Claviceps purpurea oleate ∆12-hydroxylase gene (CpFAH12) to Schizosaccharomyces pombe, putting it under the control of inducible nmt1 promoter. Since Fah12p is able to convert oleic acid to ricinoleic ...

α-Linolenic acid (ALA) deficiency and a skewed of ω6:ω3 fatty acid ratio in the diet are a major explanation for the prevalence of cardiovascular diseases and inflammatory/autoimmune diseases. There is a need to enhance the ALA content and to reduce the ratio of linoleic acid (LA) to ALA. Six ω-3 ...

We previously identified an enzyme, phosphatidylcholine diacylglycerol cholinephosphotransferase (PDCT), that plays an important role in directing fatty acyl fluxes during triacylglycerol (TAG) biosynthesis. The PDCT mediates a symmetrical interconversion between phosphatidylcholine (PC) and diacylglycerol (DAG), thus enriching PC-modified fatty acids in the DAG pool prior to forming TAG. We show ...

Here we report that the dual fluorescence emissions from protein-gold (Au) nanoclusters can greatly be modulated by metal ions and the resultant fluorescence ratiometric responses provide a novel sensory method for the identification of amino acids. The protein-gold (Au) nanoclusters were simply synthesized by the reduction of chloroauric acid with ...

A versatile transformation system for thraustochytrids, a promising producer for polyunsaturated fatty acids and fatty acid-derived fuels, was established. G418, hygromycin B, blasticidin, and zeocin inhibited the growth of thraustochytrids, indicating that multiple selectable marker genes could be used in the transformation system. A neomycin resistance gene (neo(r)), driven with ...

Skeletal muscle atrophy during bed rest is attributed, at least in part, to slower basal muscle protein synthesis (MPS). Essential amino acids (EAA) stimulate mammalian target of rapamycin (mTORC1) signaling, amino acid transporter expression, and MPS and are necessary for muscle mass maintenance, but there are no data on the ...

Escherichia coli must be able to survive extreme acidic conditions. We were interested in determining the role of the inner membrane protein YhiM in survival in acidic conditions. Previous data demonstrated that the yhiM gene was upregulated in acidic conditions (Tucker et al. in J Bacteriol. 184:6551-6558, 2002). We therefore ...

Amino acids play fundamental roles in the cell both as the building blocks of new proteins and as metabolic precursors. To adapt to their limitation during periods of protein starvation, multiple adaptive mechanisms have evolved, including a rapid cessation of new protein synthesis, an increase in amino acid biosynthesis and ...

Many membrane proteins are involved in the transport of nutrients in plants. While the import of amino acids into plant cells is, in principle, well understood, their export has been insufficiently described. Here, we present the identification and characterization of the membrane protein Siliques Are Red1 (SIAR1) from Arabidopsis (Arabidopsis ...

Sixteen variants of apolipoprotein A-I (ApoA-I) are associated with hereditary systemic amyloidoses, characterized by amyloid deposition in peripheral organs of patients. As these are heterozygous for the amyloidogenic variants, their isolation from plasma is impracticable and recombinant expression systems are needed. Here we report the expression of recombinant ApoA-I amyloidogenic ...

Hydroxycinnamoyltransferases (HCTs) catalyze the transfer of the cinnamoyl moiety from hydroxycinnamoyl-CoA to various acceptors such as shikimic acid, quinic acid, hydroxylated acid, and glycerol. Four rice HCT homologues (OsHCT1-4) to tobacco HST were cloned, and OsHCT4 was expressed in Escherichia coli as a glutathione S-transferase fusion protein. Using the purified ...

Complement plays a vital role in both the innate and adaptive immune systems. It recognizes a target, opsonizes it, generates anaphylatoxins, and directly kills cells through the membrane attack complex (MAC). This final function, which assembles C5b-9(n) on viable cell surfaces, can kill host cells through bystander lysis. Here we ...

Evolution at a protein site can be characterized from two different perspectives, by its rate and by the breadth of the set of acceptable amino acids. There is a weak positive correlation between rates and breadths of evolution, both across individual amino acid sites and across proteins. Rate and breadth ...

Lipid droplets (LDs) in non-adipocytes contain triglycerides (TG) and cholesterol esters (CE) in variable ratios. TG-rich LDs are generated when unsaturated fatty acids are administered, but the conditions that induce CE-rich LD formation are less well characterized. In the present study, we found that protein translation inhibitors such as cycloheximide ...

The association between the superoxide dismutase 2 (SOD2) Val16Ala polymorphism and the serum aminotransferase levels was retrospectively investigated in 207 valproic acid-treated patients with epilepsy. The Val/Val genotype tended to show elevated alanine aminotransferase levels (odds ratio=3.5; P=0.056). In addition, an elevated γ-glutamyltransferase level was associated with the Val/Val genotype ...

Serum uric acid (SUA) is a potential risk factor for atherosclerosis. We assessed the relationship between SUA and subclinical atherosclerosis in Korean men (n = 3010). Multidetector computed tomography (MDCT) and ultrasonographic measurements of coronary artery calcification (CAC) and carotid intima-media thickness (cIMT), respectively, are markers of subclinical atherosclerosis. Odds ...

The reference range for urinary uric acid excretion has not been precisely defined. Different urinary variables have been proposed to determine the renal contribution to increased or decreased serum urate concentrations. We examined which urinary variable best indicates uric acid excretion over a wide range of serum urate concentrations. Purine ...
