molecular function
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
    GO:0043817    phosphosulfolactate synthase activity    Catalysis of the reaction: (2R)-O-phospho-3-sulfolactate = phosphoenolpyruvate + sulfite.
    GO:0050545    sulfopyruvate decarboxylase activity    Catalysis of the reaction: 3-sulfopyruvate + H(+) = CO(2) + sulfoacetaldehyde.
biological process
    GO:0019295    coenzyme M biosynthetic process    The chemical reactions and pathways resulting in the formation of coenzyme M (2-thioethansulfonate), a coenzyme involved in the utilization of methane by methanogenic prokaryotes.
