The simplest of all peptides. It functions as a gamma-glutamyl acceptor.
Lysostaphin
A 25-kDa peptidase produced by Staphylococcus simulans which cleaves a glycine-glcyine bond unique to an inter-peptide cross-bridge of the STAPHYLOCOCCUS AUREUS cell wall. EC 3.4.24.75.
Dipeptides
Peptides composed of two amino acid units.
Carnosine
A naturally occurring dipeptide neuropeptide found in muscles.
gamma-Glutamyltransferase
An enzyme, sometimes called GGT, with a key role in the synthesis and degradation of GLUTATHIONE; (GSH, a tripeptide that protects cells from many toxins). It catalyzes the transfer of the gamma-glutamyl moiety to an acceptor amino acid.
Jejunum
The middle portion of the SMALL INTESTINE, between DUODENUM and ILEUM. It represents about 2/5 of the remaining portion of the small intestine below duodenum.
Dipeptidases
EXOPEPTIDASES that specifically act on dipeptides. EC 3.4.13.
Intestinal Absorption
Uptake of substances through the lining of the INTESTINES.
Histidine
An essential amino acid that is required for the production of HISTAMINE.
Zambia
A republic in southern Africa, south of DEMOCRATIC REPUBLIC OF THE CONGO and TANZANIA, and north of ZIMBABWE. Its capital is Lusaka. It was formerly called Northern Rhodesia.
Glycine
A non-essential amino acid. It is found primarily in gelatin and silk fibroin and used therapeutically as a nutrient. It is also a fast inhibitory neurotransmitter.
