Microbial hemicellulases

Hemicellulases are a diverse group of enzymes that hydrolyze hemicelluloses--one of the most abundant groups of polysaccharide in nature. These enzymes have many biotechnological applications and their structure/function relationships are a subject of intense research. During the past year, new high-resolution structures of catalytic and non-catalytic domains of hemicellulases have been elucidated, and, together with biochemical studies, they reveal the principles of catalysis and specificity for these enzymes.
