W-molybdopterin cofactor metabolic process

The chemical reactions and pathways involving the W-molybdopterin cofactor, essential for the catalytic activity of some enzymes. The cofactor consists of a mononuclear tungsten ion (W) coordinated by one or two molybdopterin ligands.

W-molybdopterin cofactor biosynthetic process

The chemical reactions and pathways resulting in the formation of the W-molybdopterin cofactor, essential for the catalytic activity of some enzymes. The cofactor consists of a mononuclear tungsten ion (W) coordinated by one or two molybdopterin ligands.

W-molybdopterin cofactor catabolic process

The chemical reactions and pathways resulting in the breakdown of the W-molybdopterin cofactor, essential for the catalytic activity of some enzymes. The cofactor consists of a mononuclear tungsten ion (W) coordinated by one or two molybdopterin ligands.

citrate (Si)-synthase activity

Catalysis of the reaction: acetyl-CoA + H2O + oxaloacetate = citrate + CoA, where the acetyl group is added to the si-face of oxaloacetate; acetyl-CoA thus provides the two carbon atoms of the pro-S carboxymethyl group.

silicate metabolic process

The chemical reactions and pathways involving silicates, the salts of silicic acids. Silicates are usually composed of silicon and oxygen (Si[x]O[y]), one or more metals, and possibly hydrogen. Types of silicate include unisilicates, metasilicates and hydrous silicates.

silicate transmembrane transporter activity

Enables the transfer of silicates from one side of a membrane to the other. Silicates are the salts of silicic acids, and are usually composed of silicon and oxygen (Si[x]O[y]), one or more metals, and possibly hydrogen. Types of silicate include unisilicates, metasilicates and hydrous silicates.

silicic acid import across plasma membrane

The directed movement of silicates from outside of a cell, across the plasma membrane and into the cytosol. Silicates are the salts of silicic acids, and are usually composed of silicon and oxygen (Si[x]O[y]), one or more metals, and possibly hydrogen. Types of silicate include unisilicates, metasilicates and hydrous silicates.

tenascin complex

A extracellular matrix complex involved in cell adhesion and cell migration. Typically homotrimeric or homohexameric. In mammals, four complexes exist: Tenascin-C, Tenascin-N (also known as Tenascin-W), Tenascin-X and Tenascin-R.

molybdopterin cofactor binding

Binding to a molybdopterin cofactor (Moco), essential for the catalytic activity of some enzymes, e.g. sulfite oxidase, xanthine dehydrogenase, and aldehyde oxidase. The cofactor consists of a mononuclear molybdenum (Mo-molybdopterin) or tungsten ion (W-molybdopterin) coordinated by one or two molybdopterin ligands.
