Complement system thioester-containing proteins

Both C3b and C4b bind tightly to cell surfaces, a feature that helps to direct the complement system s attack to the surfaces of invading organisms. This tight binding also involves covalent attachment of macromolecules by reaction with a preformed thioester just as with a2-macroglobulin.hd In fact, the thioester linkage was first discovered in the complement proteins. Both C3 and C4 contain the thioester...
