This is the highly conserved galactokinase signature sequencewhich appears to be present in all galactokinases irrespectiveof how many other ATP binding sites, etc that they carry [1].The function of this domain appears to be to bind galactose [2],and the domain is normally at the N-terminus of the enzymes,EC:2.7.1.6 [3]. This domain is associated with the familiesGHMP_kinases_C, Pfam:PF08544 and GHMP_kinases_N, Pfam:PF00288. Galactokinase galactose-binding signature GalKase_gal_bdg
