S177A D-allose activates AtABI5 expression in transgenic gin2 (mutant glucose-insensitive2-1 (gin2), which has a null mutation in the glucose sensor gene of AtHXK1) over-expressing wild-type AtHXK1 but not in gin2 over-expressing the catalytic mutant AtHXK1S177A, indicating that the D-allose phosphorylation by HXK to D-allose 6-phosphate (A6P) is the first step for the up-regulation of AtABI5 gene expression as well as D-allose-induced growth inhibition Arabidopsis thaliana
