OBSOLETE. Catalysis of the preferential cleavage of one bond in native collagen. Cleavage of the triple helix of collagen at about three-quarters of the length of the molecule from the N-terminus, at Gly775-Ile776 in the alpha-1(I) chain. Cleaves synthetic substrates and alpha-macroglobulins at bonds where P1' is a hydrophobic residue.
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).
