Leucylglycylglycine (DL-Leu-Gly-Gly) may be used to study the effects of branched-chain di- and tripeptides on cell envelope-associated proteinase (CEPs) activity. L-Leu-Gly-Gly may be used as a substrate to study the kinetics of tripeptide aminopeptidase (EC 3.4.11.4) and other peptidase(s) such as leucylglycylglycine aminopeptidase (EC 3.4.1.3).
"Homing" of hematopoietic progenitor cells to the bone marrow occurs during the clinical practice of bone marrow transplantation. Its mechanism is unknown, although adhesive interactions between hematopoietic cells and sinusoidal endothelium in the bone marrow may be implicated. Studies of

The development and distribution of peptidase activity in mucosal homogenates of rat small intestine has been investigated. Substrates used were glycyl-L-leucine (GL), L-seryl-L-methionine (SM), and L-leucyl-glycyl-glycine (LGG). During the first 2 weeks of life there was high peptidase activity toward
This is a method for measuring tripeptide aminopeptidase (EC 3.4.11.4) activity in serum. L- Leucylglycylglycine is used as substrate, and the reaction is followed by monitoring the absorbance increase at 340 nm when NAD+ is reduced to NADH in the

The cell-envelope-associated proteinase of Lactobacillus delbrueckii subsp. lactis CRL 581 (PrtL) has an essential role in bacterial growth and contributes to the development of the organoleptic properties of hard cheeses and to the release of bioactive health-beneficial peptides from milk

In the present study, a new analytical methodology was developed enabling the enantiomeric determination of N-derivatized di- and tri-peptides in dietary supplements using chiral micro-LC on a monolithic column consisting of poly(O-9-[2-(methacryloyloxy)-ethylcarbamoyl]-10,11-dihydroquinidine-co-2-hydroxyethyl methacrylate-co-ethylene dimethacrylate) (poly(MQD-co-HEMA-co-EDMA)). After optimization of the mobile
