Glycoside hydrolase family 113 beta-mannosidase and similar proteins. Family 113 glycoside hydrolases cleave (1->4)-beta-glycosidic linkages, such as endo-1,4-beta-mannanase. This family also includes TIM-barrel domains found in gene transfer agent proteins.

Glycoside hydrolase family 113 beta-1,4-mannanase and similar proteins. Mannan endo-1,4-beta mannosidase (E.C 3.2.1.78) randomly cleaves (1->4)-beta-D-mannosidic linkages in mannans, galactomannans and glucomannans and is also called beta-1,4-mannanase, endo-1,4-beta-mannanase, endo-beta-1,4-mannase, beta-mannanase B, beta-1, 4-mannan 4-mannanohydrolase, endo-beta-mannanase, beta-D-mannanase, 1,4-beta-D-mannan mannanohydrolase, and 4-beta-D-mannan mannanohydrolase. (1->4)-beta-linked mannans are polysaccharides with a linear polymer backbone of (1->4)-beta-linked mannose units (in plants and fungi) or alternating mannose and glucose/galactose units (glucomannan in plants and fungi, and galactomannan and galactoglucomannan in plants), such as in the hemicellulose fraction of hard- and softwoods. Complete degradation of mannan requires a series of enzymes, including beta-1,4-mannanase. According to the CAZy database beta-1,4-mannanases are grouped into various glycoside hydrolase (GH) families; GH family 113 beta-1,4-mannanases include mostly bacterial and archaeal sequences.

GTA TIM-barrel-like domain. This domain is found in the gene transfer agent protein. An unusual system of genetic exchange exists in the purple nonsulfur bacterium Rhodobacter capsulatus. DNA transmission is mediated by a small bacteriophage-like particle called the gene transfer agent (GTA) that transfers random 4.5-kb segments of the producing cell's genome to recipient cells, where allelic replacement occurs. The genes involved in this process appear to be found widely in bacteria. According to the SUPERFAMILY database this domain has a TIM barrel fold.

Putative glycoside hydrolase TIM-barrel domain in gene transfer agent and similar proteins. This domain is found in the gene transfer agent protein, such as the Rhodobacter capsulatus putative gene transfer agent protein encoded by orfg15. In the purple nonsulfur bacterium Rhodobacter capsulatus, DNA transmission is mediated via an unusual system, a small bacteriophage-like particle called the gene transfer agent (GTA) that transfers random 4.5-kb segments of the producing cell's genome to recipient cells, where allelic replacement occurs.
