racemase and epimerase activity, acting on carbohydrates and derivatives

Catalysis of a reaction that alters the configuration of one or more chiral centers in a carbohydrate molecule.

Catalysis of a reaction that interconverts cis and trans isomers. Atoms or groups are termed cis or trans to one another when they lie respectively on the same or on opposite sides of a reference plane identifiable as common among stereoisomers.

Catalysis of the reaction: L-serine + L-homocysteine = cystathionine + H2O.

Catalysis of the reaction: L-cystathionine + H2O = L-cysteine + NH3 + 2-oxobutanoate.

Catalysis of the reaction: cytidine + H2O = uridine + NH3.

Catalysis of the reaction: NADH + H+ + 2 ferricytochrome b(5) = NAD+ + 2 ferrocytochrome b(5).

Any process that modulates the frequency, rate or extent of osteoclast differentiation.

Catalysis of the reaction: 4 ferrocytochrome c + O2 = 4 ferricytochrome c + 2 H2O.

negative regulation of osteoclast differentiation

Any process that stops, prevents or reduces the rate of osteoclast differentiation.

carbon-nitrogen ligase activity, with glutamine as amido-N-donor

Catalysis of the transfer of the amide nitrogen of glutamine to a variety of substrates. GATases catalyze two separate reactions at two active sites, which are located either on a single polypeptide chain or on different subunits. In the glutaminase reaction, glutamine is hydrolyzed to glutamate and ammonia, which is added to an acceptor substrate in the synthase reaction.

ligase activity, forming carbon-carbon bonds

Catalysis of the ligation of two substances via a carbon-carbon bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate.

ligase activity, forming phosphoric ester bonds

Catalysis of the ligation of two substances via a phosphoric ester bond with concomitant breakage of a diphosphate linkage, usually in a nucleoside triphosphate.

Catalysis of the reaction: ATP + H2O = ADP + phosphate. May or may not be coupled to another reaction.

endodeoxyribonuclease activity, producing 5' phosphomonoesters
