The celA gene, encoding a glycosyl hydrolase family 3 beta-glucosidase in Azospirillum irakense, is required for optimal growth on cellobiosides.

ABSTRACT: The CelA beta-glucosidase of Azospirillum irakense, belonging to glycosyl hydrolase family 3 (GHF3), preferentially hydrolyzes cellobiose and releases glucose units from the C(3), C(4), and C(5) oligosaccharides. The growth of a DeltacelA mutant on these cellobiosides was affected. In A. irakense, the GHF3 beta-glucosidases appear to be functional alternatives for the GHF1 beta-glucosidases in the assimilation of beta-glucosides by other bacteria.
