Nitrogen uptake substrate additions

Incorporation of natural amino acids (114, 115,116, 117, 118) and homologs (119,120,121) without further chain lengthening (VII to XVI) proceeds with retention of the a-amino nitrogen (119, 120, 122). An enzyme catalyzing the oxidation and decarboxylation of the N-hydroxyamino acid VIII to the aldoxime XI (123,124) has been purified 1400-fold (125). It is stimulated by FMN, O2 uptake is observed, and the a-keto acid oxime V is not used as a substrate (124,125). Decarboxylation may occur via the a-nitroso acid IX. Incorporation of the nitro compound XIII (126) presumably occurs via the acf-nitro compound XII which was suggested by Ettlinger and Kjaer (72) as an intermediate. The addition of thiols to... [Pg.252]
