This is the highly conserved galactokinase signature sequence which appears to be present in all galactokinases irrespective of 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 families GHMP_kinases_C, Pfam:PF08544 and GHMP_kinases_N, Pfam:PF00288.	Domain
