L-Serine, L-lysyl-L-threonyl-L-threonyl-L-lysyl-

Description:

L-Serine, L-lysyl-L-threonyl-L-threonyl-L-lysyl- is a peptide composed of the amino acids serine, lysine, and threonine. This compound is characterized by its specific sequence of amino acids, which influences its biological activity and properties. Peptides like this one often exhibit unique solubility characteristics, typically being soluble in water due to the presence of polar side chains from serine and threonine. The lysine residues contribute to the overall positive charge of the peptide at physiological pH, which can affect its interaction with other biomolecules. Additionally, the presence of multiple threonine and lysine residues may enhance its potential for post-translational modifications, such as phosphorylation or acetylation, which can further modulate its function. This peptide may be of interest in biochemical research, particularly in studies related to protein synthesis, enzyme activity, or cellular signaling pathways. Its specific CAS number, 149128-48-3, allows for precise identification in chemical databases and literature.

Procollagen Type I (212-216)

CAS: 149128-48-3

A subfragment of the carboxy-terminal propeptide of type I collagen (residues 197-241) was shown to stimulate extracellular matrix biosynthesis in fibroblasts. The pentapeptide KTTKS has been found to be the minimum sequence necessary for this potent stimulation of collagen and fibronectin production in a variety of mesenchymal cells.
