ID 6.2.1.78 DE (3R)-beta-phenylalanine--CoA ligase. AN beta-phenylalanine coenzyme A ligase. CA (3R)-beta-phenylalanine + ATP + CoA = (3R)-3-amino-3-phenylpropanoyl-CoA CA + AMP + diphosphate. CC -!- The enzyme, characterized from the fungus Penicillium chrysogenum, CC acts on (3R)-beta-phenylalanine and has slight activity on some other CC amino acids including (3S)-beta-phenylalanine. CC -!- It also acts on medium-chain-length alkanoic acids as EC 6.2.1.2. CC -!- In taxol-producing trees the enzyme is involved in taxol CC biosynthesis.
