Amino-acid sequence alignment of glycoside hydrolase family 3. The regions surrounding the putative active-site region are shown. Abbreviations: TnBglB, Thermotoga neapolitana DSM 4359 β-glucosidase 3B; TmBgl, T. maritima MSB8 β-glucosidase; FnGH, Fervidobacterium nodosum glycoside hydrolase; AhBgl, Aeromonas hydrophila β-glucosidase; FspBgl, Flavobacterium sp. MED217 β-glucosidase; PaBgl, Prevotella albensis β-glucosidase; YpBgl, Yersinia pestis Nepal516 β-glucosidase; CtBglB, Clostridium thermocellum β-glucosidase B; CsBgl, C. stercorarium β-glucosidase; PspGlc, Paenibacillus sp. TS12 glucocerebrosidase; AnBgl, Aspergillus niger β-glucosidase; FmBgl, Flavobacterium meningosepticum β-glucosidase; HvBgl, barley β-D-glucan exohydrolase ExoI. Amino acids in bold have been determined experimentally as catalytic amino acids, an inverted triangle denotes the position of the nucleophile and diamonds denote the positions of verified acid/base residues. |
