GO
GO:0030246 Binding to a carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates. GO:0004553 Catalysis of the hydrolysis of any O-glycosyl bond. GO:0005515 Binding to a protein. GO:0005576 The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. GO:0016985 Catalysis of the random hydrolysis of (1->4)-beta-D-mannosidic linkages in mannans, galactomannans, glucomannans, and galactoglucomannans.
