THE CRYSTAL STRUCTURE OF HUMAN ALANINE:GLYOXYLATE AMINOTRANSFERASE

Overview

A deficiency of the liver-specific enzyme alanine:glyoxylate, aminotransferase (AGT) is responsible for the potentially lethal, hereditary kidney stone disease primary hyperoxaluria type 1 (PH1). Many, of the mutations in the gene encoding AGT are associated with specific, enzymatic phenotypes such as accelerated proteolysis (Ser205Pro), intra-peroxisomal aggregation (Gly41Arg), inhibition of pyridoxal, phosphate binding and loss of catalytic activity (Gly82Glu), and, peroxisome-to-mitochondrion mistargeting (Gly170Arg). Several mutations, including that responsible for AGT mistargeting, co-segregate and interact, synergistically with a Pro11Leu polymorphism found at high frequency in, the normal population. In order to gain further insights into the, mechanistic link between genotype and ... [(full description)]
