Abstract/OtherAbstract:
1. We report on the kinetic properties of murine liver 4,5-dioxovaleric acid:L-alanine aminotransferase (DOVA transaminase). 2. The transamination of 4,5-dioxovaleric acid (DOVA) led to the production of delta-aminolevulinic acid. 3. L-Alanine was the preferred amino group donor among the common 20 amino acids. 4. The optimum pH of the reaction was 7-8. 5. A Km of 220 microM for DOVA and a Km of 970 microM for L-alanine were obtained. 6. The reaction was inhibited by each of the following: glyoxylate, beta-chloroalanine, methylglyoxal, delta-aminolevulinate, pyruvate, heme, and gabaculine. 7. None of several xenobiotic inducers of microsomal mixed function oxidases tested had a significant effect on DOVA transaminase activity in studies performed with murine primary hepatocyte cultures.
