Protein Domain : IPR015955

Type:  Domain Name:  Lactate dehydrogenase/glycoside hydrolase, family 4, C-terminal
Description:  This entry represents a structural motif found at the C-terminal of lactate dehydrogenase ()and malate dehydrogenases (), as well as at the C-terminal of family 4 glycoside hydrolases (). These domains have an unusual fold consisting of segregated alpha-helical and beta-sheet regions, although they contain predominantly anti-parallel beta-sheets [, , ].L-lactate dehydrogenases are metabolic enzymes that catalyse the conversion of L-lactate to pyruvate, the last step in anaerobic glycolysis. L-lactate dehydrogenase is also found as a lens crystallin in bird and crocodile eyes. Malate dehydrogenases catalyse the interconversion of malate to oxaloacetate. The enzyme participates in the citric acid cycle.O-Glycosyl hydrolases are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [, ]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site. Because the fold of proteins is better conserved than their sequences, some of the families can be grouped in 'clans'. Glycoside hydrolase family 4 comprises enzymes with several known activities; 6-phospho-beta-glucosidase (); 6-phospho-alpha-glucosidase (); alpha-galactosidase (). Short Name:  Lactate_DH/Glyco_Ohase_4_C
