DEHAL1
|
Class |
Oxidoreductases;
Catalysing the reaction X-H + Y-H = X-Y;
With NAD+ or NADP+ as acceptor
|
Sysname |
L-tyrosine,iodide:NADP+ oxidoreductase (iodinating)
|
Reaction(IUBMB) |
L-tyrosine + 2 NADP+ + 2 iodide = 3,5-diiodo-L-tyrosine + 2 NADPH + 2 H+ (overall reaction) [RN: R10059];
(1a) L-tyrosine + NADP+ + iodide = 3-iodo-L-tyrosine + NADPH + H+ [RN: R09521];
(1b) 3-iodo-L-tyrosine + NADP+ + iodide = 3,5-diiodo-L-tyrosine + NADPH + H+ [RN: R09522]
