obsolete metal incorporation into metallo-oxygen cluster
OBSOLETE. The formation of a cluster of several metal atoms, including manganese or calcium, with one or more bridging (mu-bond) oxygen atoms; amino acids residues in proteins that may ligate the metal oxygen cluster are histidine, aspartate, and glutamate.
metal incorporation into metallo-sulfur cluster
The formation of a cluster of several metal atoms, including iron, nickel, molybdenum, vanadium, or copper, with one or more bridging (mu-bond) sulfur atoms; amino acids residues in proteins that may ligate the metal sulfur cluster are cysteine, histidine, aspartate, glutamate, serine and cysteine persulfide.
AP-type membrane coat adaptor complex
Any of several heterotetrameric complexes that link clathrin (or another coat-forming molecule, as hypothesized for AP-3 and AP-4) to a membrane surface; they are found on coated pits and coated vesicles, and mediate sorting of cargo proteins into vesicles. Each AP complex contains two large (a beta and one of either an alpha, gamma, delta, or epsilon) subunits (110-130 kDa), a medium (mu) subunit (approximately 50 kDa), and a small (sigma) subunit (15-20 kDa).
