AbstractHelp

O-Glycosyl hydrolases EC:3.2.1. 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 [1, 2, 3]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site [4]. Because the fold of proteins is better conserved than their sequences, some of the families can be grouped in clans.

This entry represents the catalytic TIM beta/alpha barrel common to many different families of glycosyl hydrolases. Structures have been determined for several proteins containing this domain, including family 13 glycosyl hydrolases (such as alpha-amylase) [5], beta-glycanases [6], family 1 glycosyl hydrolases (such as beta-glucosidase) [7], type II chitinases [8], 1,4-beta-N-acetylmuraminidases [9], and beta-N-acetylhexosaminidases [10].

More information about this protein can be found at Protein of the Month: alpha-Amylase [11].
