Gly-Ala-Tyr (H-Gly-Ala-Tyr-OH) is a tripeptide substrate composed of L-glycine, alanine, and L-tyrosine joined in sequence by peptide linkages. Gly-Ala-Tyr can be hydrolyzed at both extracellular and intracellular levels by Streptococcus thermophilus, Lactobacillus delbrueckii ssp. bulgaricus, Lactobacillus acidophilus, and Bifidobacterium spp. Ala-Gly-Tyr is functionally related to L-alanine, glycine and L-tyrosine. .

HY-P2543

Neuropeptide Y (3-36) (human, rat) 1 Publications Verification	Neuropeptide Y Receptor	Cardiovascular Disease Neurological Disease
Neuropeptide Y (3-36) (human, rat) is a neuropeptide Y fragment derived from humans or rats. Neuropeptide Y is an extremely abundant neurotransmitter in central and peripheral neurons, and it participates in the regulation of psychomotor activity, circadian rhythm, feeding behavior and cardiovascular function. Neuropeptide Y (3-36) (human, rat) can serve as a substrate to be sequentially degraded from its N-terminus by AfuS28, and it requires binding to AfuS28 and SedB to be decomposed into amino acids, dipeptides and tripeptides ^[1] ^[2].
