The evolution of starch-binding domain.
Amylolytic enzymes belonging to three distinct families of glycosidases (13, 14, 15) contain the starch-binding domain (SBD) positioned almost exclusively at the C-terminus. Detailed analysis of all available SBD sequences from 43 different amylases revealed its independent evolutionary behaviour with regard to the catalytic domains. In the evolutionary tree based on sequence alignment of the S...

15 صفحه اولCrystal structures of the starch-binding domain from Rhizopus oryzae glucoamylase reveal a polysaccharide-binding path.
GA (glucoamylase) hydrolyses starch and polysaccharides to beta-D-glucose. RoGA (Rhizopus oryzae GA) consists of two functional domains, an N-terminal SBD (starch-binding domain) and a C-terminal catalytic domain, which are connected by an O-glycosylated linker. In the present study, the crystal structures of the SBD from RoGA (RoGACBM21) and the complexes with beta-cyclodextrin (SBD-betaCD) an...
متن کاملStarch-binding domain shuffling in Aspergillus niger glucoamylase.
Aspergillus niger glucoamylase (GA) consists mainly of two forms, GAI [from the N-terminus, catalytic domain + linker + starch-binding domain (SBD)] and GAII (catalytic domain + linker). These domains were shuffled to make RGAI (SBD + linker + catalytic domain), RGAIDeltaL (SBD + catalytic domain) and RGAII (linker + catalytic domain), with domains defined by function rather than by tertiary st...
متن کاملMolecular Evolution of the Oxygen-Binding Hemerythrin Domain
BACKGROUND The evolution of oxygenic photosynthesis during Precambrian times entailed the diversification of strategies minimizing reactive oxygen species-associated damage. Four families of oxygen-carrier proteins (hemoglobin, hemerythrin and the two non-homologous families of arthropodan and molluscan hemocyanins) are known to have evolved independently the capacity to bind oxygen reversibly,...
