Phenylalanine ball and stick model spinning. Phenylalanine (symbol Phe or F) [3] is an essential α-amino acid with the formula C 9 H 11 NO 2.It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine.

α-Methylphenylalanine (α-MePhe or AMPA) is an artificial amino acid and a phenethylamine and amphetamine derivative. [1] It is the α-methylated analogue of phenylalanine, the precursor of the catecholamine neurotransmitters, and the amino acid analogue of amphetamine (α-methylphenethylamine), a psychostimulant and monoamine releasing agent.
Phenylalanine-tRNA synthetase (PheRS) is known to be among the most complex enzymes of the aaRS (Aminoacyl-tRNA synthetase) family. Bacterial and mitochondrial PheRSs share a ferredoxin -fold anticodon binding (FDX-ACB) domain , which represents a canonical double split alpha+beta motif having no insertions.
In mammals it is created from -lactate and L-phenylalanine by the cytosol nonspecific dipeptidase (CNDP2) protein. [1] It is classified as N-acyl-alpha-amino acid and pseudodipeptide. [11] It has also been reported that as an additive, N-L-lactoyl phenylalanine improves the taste of food, conferring an umami flavor [12].
N-Formylmethionyl-leucyl-phenylalanine (fMLF, fMLP or N-formyl-met-leu-phe) is an N-formylated tripeptide and sometimes simply referred to as chemotactic peptide is a potent polymorphonuclear leukocyte (PMN) chemotactic factor and is also a macrophage activator.
Phenylalanine hydroxylase (PAH) (EC 1.14.16.1) is an enzyme that catalyzes the hydroxylation of the aromatic side-chain of phenylalanine to generate tyrosine.PAH is one of three members of the biopterin-dependent aromatic amino acid hydroxylases, a class of monooxygenase that uses tetrahydrobiopterin (BH 4, a pteridine cofactor) and a non-heme iron for catalysis.
The enzyme phenylalanine racemase (EC 5.1.1.11, phenylalanine racemase, phenylalanine racemase (adenosine triphosphate-hydrolysing), gramicidin S synthetase I) is the enzyme that acts on amino acids and derivatives. It activates both the L & D stereo isomers of phenylalanine to form L-phenylalanyl adenylate and D-phenylalanyl adenylate, which ...
