Galactosamine 1-phosphate

Recently, Martin et al. described the synthesis of a- and p-D-glucosamine and galactosamine 1-phosphates using the more reactive trifluoromethyl oxazolines and dibenzyl phosphate [137],... 

This enzyme [EC 2.7.1.6] catalyzes the reaction of ATP with D-galactose to produce ADP and D-galactose 1-phosphate. o-Galactosamine can also act as the substrate.
