Valylleucine (Val-Leu; H-Val-Leu-OH) is a branched-chain dipeptide that can enter cells independently via bacterial dipeptide transport systems, and is hydrolyzed by dipeptidases to release Val and Leu. Valylleucine, as a model peptide, has its α-amino pK determined to be 7.90 by combining FDNB reaction kinetics with potentiometric titration.

Description

Valylleucine (Val-Leu; H-Val-Leu-OH) is a branched-chain dipeptide that can enter cells independently via bacterial dipeptide transport systems, and is hydrolyzed by dipeptidases to release Val and Leu. Valylleucine, as a model peptide, has its α-amino pK determined to be 7.90 by combining FDNB reaction kinetics with potentiometric titration[1][2].

In Vitro

Valylleucine (0.43 mM; up to 6 hours) relieves O-methylthreonine-induced growth inhibition in Escherichia coli 15 after a lag period of approximately 2 hours, matching the effectiveness of free valine and leucine thereafter[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
