Other enzymes also belong to this family including carboxyvinyl-carboxyphosphonate phosphorylmutase ( ) which catalyses the conversion of 1-carboxyvinyl carboxyphosphonate to 3-( hydrohydroxyphosphoryl ) pyruvate carbon dioxide, and phosphoenolpyruvate mutase ( ), which is involved in the biosynthesis of phosphinothricin tripeptide antiobiotics.

:The enzyme shows specific recognition of a C-terminal tripeptide, Xaa-Yaa-Zaa, in which Xaa is preferably Ala or Leu, Yaa is preferably Ala or Tyr, and Zaa is preferably Ala, but then cleaves at a variable distance from the C-terminus.

"' Trofinetide "'( "'NNZ-2566 "') is a drug developed by Neuren Pharmaceuticals that acts as an analogue of the neuropeptide ( 1-3 ) IGF-1, which is a simple tripeptide with sequence IGF-1 within the brain.

Standard therapy is a combination of limb-salvage orthopedic surgery when possible ( or amputation in some cases ) and a combination of high-dose methotrexate with leucovorin rescue, intra-arterial cisplatin, adriamycin, ifosfamide with mesna, BCD ( bleomycin, cyclophosphamide, dactinomycin ), etoposide, and muramyl tripeptide.

The tripeptide Arg-Gly-Asp ( "'RGD "') was originally identified as the sequence within fibronectin that mediates cell attachment, and has been found in numerous proteins, including the integrins, a family of cell-surface proteins, which act as receptors for cell adhesion molecules.

Production of classic ?-lactams in both fungi and bacteria occur through two steps : First, the condensation of-cysteine,-valine, and-?-aminoadipic acid by ACV synthetase ( ACVS, a nonribsomal peptide synthetase ) and then cyclization of this formed tripeptide by isopenicillin N synthetase ( IPNS ).
37.
The linear tripeptide ?-( L-?-aminoadipoyl )-L-cysteinyl-D-valine ( LLD-ACV ) must first be assembled from its component amino acids by N-( 5-amino-5-carboxypentanoyl )-L-cysteinyl-D-valine synthase ( ACV synthase ).
38.
The tripeptide FPP ( fertilization promoting peptide ) produced by the male is essential for capacitation " ( high levels of FPP prevent capacitation, the proper concentration occurs after ejaculation in the female reproductive tract where the concentration drops after mixing with vaginal secretions and / or becomes less active due to the pH of the vagina " ).
39.
The three dimensional NMR study of this toxin showed that it consists of a tripeptide glycine-" N "-methylvaline-alanine, a hydroxycarboxylic acid and a 9-" t "-butyl-6, 8-dimethyl-6, 8-diene attached to the C5 atom of the cyclic peptide backbone.

A web search for " Tripeptide-37 " turns up very little, and most of what is found refers to what appear to be chemical derivatives of " Tripeptide-37 " ( palmitoyl tripeptide-37, elaidoyl tripeptide-37, etc . ) There doesn't appear to be anything from a reliable source upon which to build an acceptable article.
