Fig. 6From: Comparative genomics of human Lactobacillus crispatus isolates reveals genes for glycosylation and glycogen degradation: implications for in vivo dominance of the vaginal microbiotaSchematic overview of the organization of the putative pullulanase type I encoding gene in Lactobacillus crispatus. The enzyme comprises three conserved domains including an N-terminal carbohydrate-binding module family 41 with specific carbohydrate-binding sites, a catalytic module belonging to the pullulanase super family and a C-terminal bacterial surface layer protein (SLAP). The mutations (indicated by arrows) were located in an unconserved area that encodes a putative signal peptide (SP) that may be involved in subcellular localization. Abbreviations: SP: signal peptide; CBM41: carbohydrate-binding module family 41; PulA: pullulanase; SLAP: surface layer proteinBack to article page
