nucleotide-binding domain (NBD) of Vibrio cholerae glucosamine kinase GspK and similar proteins
The family includes a group of uncharacterized proteins similar to Vibrio cholerae glucosamine kinase GspK (EC 2.7.1.8), also called GlcN kinase. It acts as ATP-dependent kinase, which is specific for glucosamine. GspK does not show kinase activity with any other sugar.
