From: Thermus thermophilus as source of thermozymes for biotechnological applications: homologous expression and biochemical characterization of an α-galactosidase

Fig. 1

Sequence homology of α-galactosidases from different sources. The amino acid sequences of Thermus thermophilus HB27 (Accession No. AAS82402), Thermus sp. strain T2 (75%), Thermus brockianus (73%), Thermotoga neapolitana (36%), Thermotoga maritima (35%), Sulfolobus solfataricus (39%) and Homo sapiens (23%) were aligned for optimal sequence similarity using the program CLUSTAL W. a The consensus motif ([LIVMFY]-x(2)-[LIVMFY]-x-[LIVM]-D-D-x-[WY]) is characteristic of α-galactosidases; b amino acid stretches including two conserved cysteine residues; c amino acid stretches surrounding the aspartic acids responsible for the nucleophilic and acid–base catalytic mechanism. Conserved amino acids are highlighted with asterisk in T. thermophilus HB27 sequence
