Description	Strukturní vlastnosti a elektrostatika chladově-aktivní beta-galaktosidasy byla presentována (cs) Arthrobacter sp. C2-2, a soil bacteria found on an island near Antarctica, belongs to psychrotrophic, i.e. cold tolerant, microorganisms. Structure of its betagalactosidase (hydrolase cleaving lactose into galactose and glucose), iso-enzyme C-2-2-1, was solved up to 1.9 Å resolution. The beta-galactosidase belongs to glycosyl hydrolase structural family 2 and has 30% sequence identity with Escherichia coli beta-galactosidase. In spite of the chain similarity, both enzymes differ in their oligomerization states. Escherichia coli beta-galactosidase is known to be active only in the form of tetramers, while the cold-active Arthrobacter sp. C2-2 beta-galactosidase forms compact hexamers with active sites oriented into an internal cavity, connected by three types of channels with exterior solvent. Additionally, sequence differences between both enzymes exist in the active site. Arthrobacter sp.
