Catalysis of the reaction: (S)-lactate + NAD+ = pyruvate + NADH + H+.

Catalysis of the stereospecific transfer of amino acids, organic acids containing one or more amino substituents, across a biological membrane.

positive regulation of bone mineralization

Any process that activates or increases the rate of bone mineralization.

Any process that modulates the redox environment of a cell or compartment within a cell.

Interacting selectively with spectrin, a protein that is the major constituent of the erythrocyte cytoskeletal network. It associates with band 4.1 (see band protein) and actin to form the cytoskeletal superstructure of the erythrocyte plasma membrane. It is composed of nonhomologous chains, alpha and beta, which aggregate side-to-side in an antiparallel fashion to form dimers, tetramers, and higher polymers.

A series of molecular signals generated as a consequence of any member of the BMP (bone morphogenetic protein) family binding to a cell surface receptor.

Catalysis of the reaction: GTP + (5')PP-pur-mRNA = diphosphate + G(5')PPP-pur-mRNA (mRNA containing a guanosine residue linked 5' through three phosphates to the 5' position of the terminal residue).

Catalysis of the reaction: ATP + 3-methylcrotonyl-CoA + HCO3- = ADP + phosphate + 3-methylglutaconyl-CoA.

Catalysis of the reaction: Na+(out) + H+(in) = Na+(in) + H+(out).

Catalysis of the reaction: 5,10-methylenetetrahydrofolate + NAD(P)+ = 5,10-methenyltetrahydrofolate + NAD(P)H + H+.

Catalysis of the reaction: 5,10-methylenetetrahydrofolate + NAD+ = 5,10-methenyltetrahydrofolate + NADH + H+.

Catalysis of the reaction: 5,10-methylenetetrahydrofolate + NADP+ = 5,10-methenyltetrahydrofolate + NADPH + H+.

Reactions triggered in response to the presence of pathogenic bacteria that act to protect the cell or organism.

Catalysis of the reaction: 5-methyltetrahydrofolate + NADP+ = 5,10-methylenetetrahydrofolate + NADPH + H+.

transferase activity, transferring pentosyl groups

Catalysis of the transfer of a pentosyl group from one compound (donor) to another (acceptor).
