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.

B-1b B cell differentiation

The process in which B cells acquire the specialized features of B-1b B cells. B-1b B cells are B-1 cells that do not express CD5.

B-1a B cell differentiation

The process in which B cells acquire the specialized features of B-1a B cells. B-1a B cells are B-1 cells that express CD5 and arise from fetal liver precursors.

B-1 B cell proliferation

The expansion of a B-1 B cell by cell division. Follows B cell activation.

B-1 B cell lineage commitment

The process in which an immature B cell becomes committed to become a B-1 B cell.

intraciliary transport particle B binding

Binding to an intraciliary transport particle B (IFT B) complex.

obsolete pheophytinase b activity

OBSOLETE. Catalysis of the reaction: pheophytin b + H2O = H+ + pheophorbide b + phytol.

follicular B cell differentiation

The process in which a B cell in the spleen acquires the specialized features of a follicular B cell. Follicular B cells are major population of mature recirculating B cells in the spleen and are located in the B-cell follicle region.
