We found Cel3B from T. reesei (TrCel3B) in a single cluster with
all of the highly active Aspergillus b-glucosidases. TrCel3B has a
predicted length of 874 amino acids and is encoded by the gene
cel3b, containing a putative coding region of 2622 bp that is interrupted
by two introns of length 514 and 55 bp. Sequence alignment
shows that the protein shares 47% identity with its counterparts
from A. aculeatus and Aspergillus oryzae (Fig. S1).
