ID 1.2.1.101 DE L-tyrosine reductase. CA AMP + diphosphate + L-tyrosinal + NADP(+) = ATP + H(+) + L-tyrosine + CA NADPH. CC -!- The enzyme, characterized from the ascomycete fungus Aspergillus CC flavus, is specific for L-tyrosine. CC -!- It contains three domains - an adenylation domain, a peptidyl-carrier CC protein (PCP) domain, and a reductase domain, and requires activation CC by attachment of a phosphopantetheinyl group. CC -!- The enzyme activates its substrate to an adenylate form, followed by CC a transfer to the PCP domain. CC -!- The resulting thioester is subsequently transferred to the reductase CC domain, where it is reduced to the aldehyde. DR B8NTZ9, LNAA_ASPFN ; B8NWW5, LNBA_ASPFN ; //
