About 30 mutants of Pseudomonas aeruginosa PAO defective in the high-affinity branched-chain amino acid transport system (LIV-I) were isolated by the selection for resistance to 4-aza-DL-leucine, a toxic leucine analog for LIV-I. All of the mutants were complemented by plasmid

Members of the genus Shewanella inhabit various environments; they are capable of synthesizing various types of low-melting-point fatty acids, including monounsaturated fatty acids (MUFA) and branched-chain fatty acids (BCFA) with and without eicosapentanoic acid (EPA). The genes involved in fatty

Ralstonia eutropha PHB-4 expressing Pseudomonas sp. 61-3 polyhydroxyalkanoate (PHA) synthase 1 (PhaC1Ps) synthesizes PHA copolymer containing 3-hydroxybutyrate (3HB) and a small amount (0.5 mol%) of 3-hydroxy-4-methylvalerate (3H4MV) from fructose as a carbon source. In this study, enhanced incorporation of 3H4MV

The growth of Escherichia coli is inhibited by an antibiotic compound, azaserine (O-diazoacetyl-L-serine). Previous studies revealed the biochemical properties of azaserine, which involves inhibition of various enzymatic reactions as well as introduction of DNA breakage. However, genetically, nothing has been
