ligandin

glu·ta·thi·one S-·trans·fer·ase

a class of enzymes that catalyzes the reaction of glutathione with an acceptor molecule (for example, an arene oxide) to form an S-substituted glutathione; a key step in detoxification of many substances; start of the mercapturic acid pathway.
Synonym(s): ligandin

ligandin

an hepatic transport protein; measurement of it in serum and urine may be a means of estimating the severity of hepatocellular necrosis.
