Valylleucine

(Synonyms: Val-Leu; H-Val-Leu-OH)

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.

Activité biologique

Description

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

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
