Arthrobacter citreus

Structural modification of evonine (54)was sought to provide compounds which might possess enhanced insecticidal activity. Thus, treatment of evonine with Arthrobacter citreus selectively removed acetyl groups to yield pentadeacetylevonine as the sole product [183]. 

In view to access both stereoisomers of a chiral amine via transamination by choice of an appropriate (R)- or (S)-selective co-TA, screening studies were undertaken which revealed an impressive number of (S)-co-TAs and some more rarely occurring (/ )-selective enzymes [1719-1722]. The most widely used enzymes are obtained from Vibrio fluvialis [1723], Chromobacterium violaceum [1724, 1725], Pseudomonas aeruginosa [1726], Bacillus megaterium [1727], and Alcaligenes denitrificans [1728]. Thermostable mutants were derived from an co-TA from Arthrobacter citreus [1729].
