In enzymology a phenylalanine adenylyltransferase (EC 2.7.7.54) is an enzyme that catalyzes the chemical reactionATP + L-phenylalanine diphosphate + N-adenylyl-L-phenylalanineThus the two substrates of this enzyme are ATP and L-phenylalanine whereas its two products are diphosphate and N-adenylyl-L-phenylalanine.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
