Abstract/OtherAbstract:
Eleven different bacteria, isolated by enrichment procedures on alpha-aminoisobutyric (AIB) as sole fixed nitrogen source, were examined for the mechanism by which they attacked the amino acid. All eleven organisms, including one which grew well on isopropylamine, converted AIB to acetone and CO(2) and showed an absolute dependence upon pyruvate for this reaction. No organism isolated degraded AIB to isopropylamine as the primary reaction. The data suggested that the usual mode of attack upon this amino acid is by an overall reaction comprised of two half reactions, one a decarboxylation-dependent transamination and the other a normal exchange transamination.
