Enzyme reactions

• Enzyme class: E.C.2.4.2.18 - anthranilate phosphoribosyltransferase.
• Pathway: Tryptophan Biosynthesis
• Reaction: N-(5-phospho-beta-D-ribosyl)anthranilate + diphosphate = 5-phospho-alpha- D-ribose 1-diphosphate + anthranilate

N-(5-phospho-beta-D-ribosyl)anthranilate (Bound ligand (Het Group name = PRP) matches with 40.91% similarity) + diphosphate (Bound ligand (Het Group name = 62L) matches with 50.00% similarity) = 5-phospho-alpha- D-ribose 1-diphosphate + anthranilate
