Catalysis of the reaction: 2 3-acyl-sn-glycero-1-phospho-(1'-sn-glycerol) = 3-acyl-sn-glycero-1-phospho-(3'-acyl-1'-sn-glycerol) + sn-glycero-1-phospho-(1'-sn-glycerol).
Catalysis of the synthesis of the HKK-1 carbohydrate epitope; adds a sulfate group to a precursor, GlcA-beta-(1->3)-Gal-beta-(1->4)-GlcNAc-beta-(1->R), forming sulfo-3GlcA-beta-(1->3)-Gal-beta-(1->4)-GlcNAc-beta-(1->R).
Catalysis of the reaction: 1-18:1-2-16:0-monogalactosyldiacylglycerol + O2 + a reduced electron acceptor = 1-18:1-2-16:1-monogalactosyldiacylglycerol + 2 H2O + an oxidized electron acceptor.
