The chemical reactions and pathways involving cyclohexylsulfamate, also known as cyclamic acid. Sodium cyclohexylsulfamate (CHS-Na) was a widely used sweetening agent but was banned because of the suspicion of carcinogenicity and metabolic conversion to cyclohexylamine (CHA), a toxic substance. It is now used as a fungicide.
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).
