citrate ions are shown to bind at only three well-defined sites involving both ion pairs and hydrogen bonds. Molecular dynamics simulations evidence that citrate binding has a remarkable conformational influence on the 3D structure of carnosinase, increasing the binding affinity of carnosine to the catalytic site

UNIPROT
COMMENTARY hide
LITERATURE
metabolism
carnosine and anserine are mainly hydrolyzed by carnosinase, a low but significant amount is excreted in the urine. Carnosine reaches a steady state of very low concentration in serum, while anserine sustains higher concentrations than that of carnosine due to its greater stability vis-a-vis carnosinase after ingesting histidine-dipeptide rich diet
malfunction
-
HeLa-CN1 cells have a lower cell survival than do non-transfected cells or HeLa cells transfected with an empty or a mock vector. Viability in HeLa cells measured after H2O2 treatment is significantly higher than the viability of HeLa-CN1 cells after the same oxidant insult, indicating an increased susceptibility to oxidative stress of cells overexpressing carnosinase
physiological function
-
CN1 activity is lower in children and increases with age with no differences in protein concentration. CN1 activity is considerably higher in serum than in cerebrospinal fluid
