additional information
?
-
dipeptides, tripeptides, tetrapeptides and pentapeptides are synthesized in the reaction mixtures containing Val, Leu, or Met as substrate. When Ile is used, the longest peptides are tetrapeptides. No peptides are detected when the other 15 amino acids are used as substrates. When Leu, Ile, or Met is used as substrate with Val, heteropeptides containing two residues of Leu, Ile, and Met are detected. No heteropeptides containing Tyr. Pro, Cys, Asp or Glu are detected. When other amino acids that are not usable for homopeptide synthesis are used as substrate, heteropeptides containing only one amino acid residue of these amino acids are detected. Substrate recognition at the N-terminus influences the resulting heteropeptide sequence. The enzyme does not participate in peptide-to-peptide ligation. Very low activity with D-amino acids

the enzyme catalyzes the synthesis of oligopeptides from unprotected L-amino acids in an ATP-dependent manner. Synthesis of various oligopeptides consisting of two to five amino acids, e.g. synthesis of Val-Val-Val tripeptide by the enzyme RizB. The enzyme shows highest activity with Val, Ile, Leu, and Met as substrates. In the reaction with Val, tetramers are the longest products synthesized, trimer are formed with Co2+. RizB shows specificity toward N-terminal substrates, but is relaxed in the specificity for the C-terminus, mass spectrometric reaction analysis, overview
