Characterization of a Beta-glucosidase Aggregating Factor Responsible for the Null Beta-glucosidase Phenotype in Maize (Zea mays L.)
… but does not bind to their sorghum homolog Dhurrinase-1 (Dhr1; Sorghum beta-glucosidase), that shares 70% sequence identity with Glu1 and Glu2. Therefore, these proteins provide an excellent system to study functional differences at nonconserved residues and elucidate the mechanism of enzyme …

Cloning and sequencing of a β-glucosidase of cDNA from Sorghum bicolor (L.) Moench and analysis of expression in seedlings
A full-length β-glucosidase encoding cDNA is isolated and sequenced from Sorghum bicolor (L) Moench. Using 5’- and 3’- end specific probes derived from the cDNA clone, the multiplicity of β-glucosidase genes and their expression in different tissues were studied. Southern blotting data showed that …

Determination of the Binding Site and the Key Amino Acids on Maize β-Glucosidase Isozyme Glu1 Involved in Binding to β-Glucosidase Aggregating Factor (BGAF)
… comparison between sorghum β-glucosidases (dhurrinases, Dhr1 and Dhr2), to which BGAF does not bind, and maize β-glucosidases, and an examination of the 3-D structure of Glu1 suggested that the BGAF binding site on Glu1 is much smaller than predicted previously. To define more precisely the …

Mechanism of Substrate Specificity and Catalysis in Retaining β-Glucosidases From Maize and Sorghum
… DIMBOAGlc, while the sorghum β-glucosidase Dhr1 (dhurrinase-1) hydrolyzes exclusively its natural substrate dhurrin. For the expression of mature β-glucosidase isozymes Glu1 and Glu2 of maize and Dhr1 of sorghum, complementary DNAs were amplified by PCR and cloned into the expression vector …
