With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
L-phenylalanine:NAD+ oxidoreductase (deaminating)
Reaction(IUBMB)
L-phenylalanine + H2O + NAD+ = phenylpyruvate + NH3 + NADH + H+ [RN:R00688]
Reaction(KEGG)
Substrate
L-phenylalanine [CPD:C00079];
H2O [CPD:C00001];
NAD+ [CPD:C00003]
Product
phenylpyruvate [CPD:C00166];
NH3 [CPD:C00014];
NADH [CPD:C00004];
H+ [CPD:C00080]
Comment
The enzymes from Bacillus badius and Sporosarcina ureae are highly specific for L-phenylalanine; that from Bacillus sphaericus also acts on L-tyrosine.
