ID 1.14.11.45 DE L-isoleucine 4-hydroxylase. CA 2-oxoglutarate + L-isoleucine + O2 = (4S)-4-hydroxy-L-isoleucine + CO2 + CA succinate. CC -!- The enzyme, characterized from the bacterium Bacillus thuringiensis, CC can also catalyze the hydroxylation of L-leucine, L-norvaline, CC L-norleucine, and L-allo-isoleucine, as well as the sulfoxidation of CC L-methionine, L-ethionine, S-methyl-L-cysteine, S-ethyl-L-cysteine, CC and S-allyl-L-cysteine.
