CRYSTAL STRUCTURE OF GLVA FROM BACILLUS SUBTILIS, A METAL-REQUIRING, NAD-DEPENDENT 6-PHOSPHO-ALPHA-GLUCOSIDASE
Overview
GlvA, a 6-phospho-alpha-glucosidase from Bacillus subtilis, catalyzes the hydrolysis of maltose-6'-phosphate and belongs to glycoside hydrolase family GH4. GH4 enzymes are unique in their requirement for NAD(H) and a divalent metal for activity. We have determined the crystal structure of GlvA in complex with its ligands to 2.05 A resolution. Analyses of the active site architecture, in conjunction with mechanistic studies and precedent from the nucleotide diphosphate hexose dehydratases and other systems, suggest a novel mechanism of glycoside hydrolysis by GlvA that involves both the NAD(H) and the metal.
About this Structure
1U8X is a Single protein structure of sequence from Bacillus subtilis. This structure supersedes the now removed PDB entry 1nrh. Full crystallographic information is available from OCA.
