L-2-Amino-5-phenylpentanoic acid
L-2-Amino-5-phenylpentanoic acid. Group: Biochemicals. Grades: Reagent Grade. Pack Sizes: 100mg, 250mg, 1g, 5g, 25g. US Biological Life Sciences.
This enzyme, characterized from the yeast Saccharomyces cerevisiae, catalyses the reduction of L-2-aminoadipate to (S)-2-amino-6-oxohexanoate during L-lysine biosynthesis. An adenylation domain activates the substrate at the expense of ATP hydrolysis, and forms L-2-aminoadipate adenylate, which is attached to a peptidyl-carrier protein (PCP) domain. Binding of NADPH results in reductive cleavage of the acyl-S-enzyme intermediate, releasing (S)-2-amino-6-oxohexanoate. Different from EC 1.2.1.31, L-aminoadipate-semialdehyde dehydrogenase, which catalyses a similar transformation in the opposite direction without ATP hydrolysis. Group: Enzymes. Synonyms: LYS2; α-aminoadipate reductase. Enzyme Commission Number: EC 1.2.1.95. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-1199; L-2-aminoadipate reductase; EC 1.2.1.95; LYS2; α-aminoadipate reductase. Cat No: EXWM-1199.
