What is Ac-Lys-OH?

Chemical properties

Nalpha-Acetyl-L-Lysine is white to almost white crystalline powder

The Uses of Ac-Lys-OH

Nalpha-Acetyl-L-Lysine is an antibacterial lysine analogue that targets lysine riboswitches. Nalpha-Acetyl-L-Lysine is used in the metabolomic characterization of ovarian epithelial carcinomas which allows fo r better therapeutic management of patients. The presence of Nalpha-Acetyl-L-Lysine and other N-acetylated amino acids in the urine can be used to detect aminoacylase I deficiency.

The Uses of Ac-Lys-OH

Nα-Acetyl-L-lysine is a biologically available N-terminal capped form of the proteinogenic α amino acid L-lysine. Nα-Acetyl-L-lysine is a substrate used to study and characterize lysyl oxidize(s).

Definition

ChEBI: An acetyl-L-lysine where the acetyl group is located at the N2-posiiton.
