Microorganisms (A), or their enzymatic extracts, able to utilise cyclopentene derivatives (VII) as sole carbon (or carbon and nitrogen) source are new. R1 = 1-4C alkyl or alkoxy, or aryl or aryloxy. Also new are (1) N-acetylamino-alcohol hydrolases (NAAH) from (A) able to hydrolyse (VII), and their functionally equivalent variants or mutants; (2) production of (1R,4S) and/or (1S,4R)-1-amino-4-hydroxymethyl-2-cyclopentene (II), or their derivatives N-substituted by COR1, by reacting (VII) with at least one of (A), its enzymatic extract, NAAH and penicillin G acylase. |
