4.2.2.11	evolution	Alg2A belongs to the polysaccharide lyase family 7, but has a different endolytic reaction mode from other alginate lyases from polysaccharide lyase family 7 owing to high yields of penta-, hex-, and hepta-saccharides in the hydrolysis products of Alg2A, overview	730135	
4.2.2.11	evolution	AlyA1PL7 is an endolytic guluronate lyase and belongs to the PL7 family, subfamily 1, the genome of Zobellia galactanivorans contains seven putative alginate lyase genes, five of which are localized within two clusters comprising additional carbohydrate-related genes, phylogenetic analysis. Despite a common jelly roll-fold, these striking differences of the mode of action are explained by a distinct active site topology, an open cleft in AlyA1PL7, whereas AlyA5 displays a pocket topology due to the presence of additional loops partially obstructing the catalytic groove. In contrast to PL7 alginate lyases from terrestrial bacteria, both enzymes proceed according to a calcium-dependent mechanism	-, 730018

4.2.2.11	physiological function	alginate lyase consists of three domains, i.e. a carbohydrate-binding domain, a family 32 CBM domain, and an alginate lyase domain belonging to polysaccharide lyase family 7 (PL7). The CBM32 domain does not contribute to enhancing AlyQ's activity under the assayed conditions but can bind to cleaved but not intact alginate. The CBM32 and catalytic domains do not interact with one another. The CBM32 domain contains a conserved Arg that may bind to the carboxyl group of alginate. The catalytic domain shares a conserved substrate-binding groove, and the presence of two negatively charged Asp residues may dictate substrate specificity especially at subsite +1	749331
