Catalysis of the reaction: S-adenosyl-L-methionine + nicotinamide = S-adenosyl-L-homocysteine + 1-methylnicotinamide.

Thin cylindrical membrane-covered projections on the surface of an animal cell containing a core bundle of actin filaments. Present in especially large numbers on the absorptive surface of intestinal cells.

Catalysis of the reaction: protein L-methionine + oxidized thioredoxin = protein L-methionine S-oxide + reduced thioredoxin.

Dense covering of microvilli on the apical surface of epithelial cells in the intestine and kidney; the microvilli aid absorption by increasing the surface area of the cell.

Catalysis of the reaction: sarcosine + H2O + O2 = glycine + formaldehyde + H2O2.

An invagination of the cell membrane of many eukaryotic cells, concerned in receptor-mediated selective transport of many proteins and other macromolecules across the cell membrane. During endocytosis it is converted into a coated vesicle. The coat is of clathrin.

Catalysis of the reaction: beta-D-glucose + NAD(P)+ = D-glucono-1,5-lactone + NAD(P)H.

Catalysis of the reaction: (5Z,13E)-(15S)-9-alpha,11-alpha-epidioxy-15-hydroxyprosta-5,13-dienoate = (5Z,13E)-(15S)-6,9-alpha-epoxy-11-alpha,15-dihydroxyprosta-5,13-dienoate.

Interacting selectively with any carbohydrate.

Catalysis of the reaction: sphinganine 1-phosphate = phosphoethanolamine + palmitaldehyde.

Interacting selectively with any polysaccharide.

Catalysis of the reaction: (5Z,13E)-(15S)-9-alpha,11-alpha-epidioxy-15-hydroxyprosta-5,13-dienoate = (5Z,13E)-(15S)-11-alpha,15-dihydroxy-9-oxoprosta-5,13-dienoate.

The differentiation of endothelial cells from progenitor cells during blood vessel development, and the de novo formation of blood vessels and tubes.

Catalysis of the reaction: (5Z,13E)-(15S)-9-alpha,11-alpha,15-trihydroxyprosta-5,13-dienoate + NADP+ = (5Z,13E)-(15S)-11-alpha,15-dihydroxy-9-oxoprosta-5,13-dienoate + NADPH.

Catalysis of the reaction: S-adenosyl-L-methionine + a thiopurine = S-adenosyl-L-homocysteine + a thiopurine S-methylether.
