Sequence alignment of Bgl1 (PDB entry 9gci) with its closest sequence and structural homologues: β-glucosidase A from Clostridium cellulovorans (the closest sequence and structural homologue; PDB entry 3ahx; Jeng et al., 2011), β-glucosidase from the haemophilic Halothermothrix orenii strain H 168 (PDB entry 4ptv; Hassan et al., 2015), β-glucosidase from Thermotoga maritima (PDB entry 1od0; Zechel et al., 2003), β-glucosidase from T. neapolitana (PDB entry 5idi; Kulkarni et al., 2017), β-glucosidase from Paenibacillus polymyxa (PDB entry 1tr1; Sanz-Aparicio et al., 1998), β-glucosidase from Thermus thermophilus strain HB8 (PDB entry 4bce; Teze et al., 2014), β-glucosidase from Niallia circulans subsp. alkalophilus (PDB entry 1qox; Hakulinen et al., 2000), a metagenomic glucose-tolerant β-glucosidase (PDB entry 5xgz; Matsuzawa et al., 2017) and β-glucosidase from Thermus nonproteolyticus (PDB entry 1np2; Wang et al., 2003). Identical and similar residues are shown in white on a red background and in red on a white background, respectively. The residues of interest (cyan triangles) are also indicated on the same line. The secondary-structure elements are shown for the Bgl1 structure, with α-helices, 310-helices, β-strands and β-turns being denoted α, η, β and TT, respectively. The shaded regions labelled ins1 and ins2 depict the two insertions in the sequence of Bgl1. The sequence identity, coverage and Z-score for the closest structural homologues are summarized in Table 2. |
