obsolete 4-hydroxyphenylacetate,NADH:oxygen oxidoreductase (3-hydroxylating) activity https://github.com/geneontology/go-ontology/issues/23202 true OBSOLETE. Catalysis of the reaction: 4-hydroxyphenylacetate + NADH + H+ + O2 = 3,4-dihydroxyphenylacetate + NAD+ + H2O. 4-hydroxyphenylacetate 3-hydroxylase activity p-hydroxyphenylacetate 3-hydroxylase activity molecular_function RHEA:16681 (RHEA:16681 has been replaced by RHEA:30595); The EC assigned this term does not use NAD but FAD GO:0052881 already assigned RHEA:30595 using FADH; Since GO:0018660 was assigned to RHEA 16681 with NAD vs FAD; 3 IEA; suggest obsoletion of GO:0018660 4-hydroxyphenylacetate 3-monooxygenase activity p-hydroxyphenylacetate hydroxylase activity 4 HPA 3-hydroxylase activity GO:0018660
