ID 1.3.3.16 DE oxazoline dehydrogenase. AN azoline oxidase. AN cyanobactin oxidase. AN thiazoline oxidase. CA (1) (1S,4R)-2-(C-substituted-aminomethyl)-4-acyl-2-thiazoline-[protein] + CA O2 = (S)-2-(C-substituted-aminomethyl)-4-acyl-1,3-thiazole-[protein] + CA H2O2. CA (2) (S,S)-2-(C-substituted-aminomethyl)-4-acyl-2-oxazoline-[protein] + CA O2 = (S)-2-(C-substituted-aminomethyl)-4-acyl-1,3-oxazole-[protein] + CA H2O2. CA (3) (S,S)-2-(C-substituted-aminomethyl)-4-acyl-5-methyl-2-oxazoline- CA [protein] + O2 = (S)-2-(C-substituted-aminomethyl)-4-acyl-5-methyl-1,3- CA oxazole-[protein] + H2O2. CC -!- Contains FMN. CC -!- This enzyme oxidizes 2-oxazoline, 5-methyl-2-oxazoline, CC and 2-thiazoline within peptides, which were formed by EC 6.2.2.2 and CC EC 6.2.2.3 to the respective pyrrole-type rings. CC -!- The enzyme is found as either a stand-alone protein or as a domain CC within a multifunctional protein (the G protein) that also functions CC as a peptidase. //
