Catalysis of the reaction: L-cysteine + O2 = 3-sulfinoalanine.

Any process that modulates the frequency, rate or extent of the chemical reactions involving carbohydrates.

Catalysis of the reaction: 2,5-diamino-6-ribitylamino-4(3H)-pyrimidinone 5'-phosphate = 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione 5'-phosphate.

Catalysis of the reaction: S-adenosyl-L-methionine + glycine = S-adenosyl-L-homocysteine + sarcosine.

Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + phosphatidylinositol = UDP + N-acetyl-D-glucosaminylphosphatidylinositol.

A heterodimeric complex that catalyzes the trimming of glucose residues from N-linked core glycans on newly synthesized glycoproteins.

Catalysis of the conversion of phosphatidylinositol-3-phosphate, phosphatidylinositol-4-phosphate, and phosphatidylinositol-3,5-bisphosphate, but not PI-4,5-bisphosphate, to phosphatidylinositol; PPIPase activity is a key regulator of membrane trafficking and actin cytoskeleton organization.

The process by which all major lipid classes are redistributed within the plasma membrane following cell activation or injury, resulting in surface exposure of phosphatidylserine (PS) and phosphatidylethanolamine (PE). Cell surface-exposed PS can serve as receptor sites for coagulation enzyme complexes, and contributes to cell clearance by the reticuloendothelial system.

Heterotrimeric enzyme complex, which in humans is composed of two large subunits of the same size, and one smaller subunit. Functions in the addition of nucleotide-activated sugars onto the polypeptide.

Increases the rate of GTP hydrolysis by the GTPase Ral.

Interacting selectively with a SH3 domain (Src homology 3) of a protein, small protein modules containing approximately 50 amino acid residues found in a great variety of intracellular or membrane-associated proteins.

Catalysis of the insertion of a dCMP residue opposite a template abasic site in DNA.

Processes involved with the formation and assembly of the nucleolus, a small, dense body one or more of which are present in the nucleus of eukaryotic cells.
