C3a formation occurs through activation and cleavage of complement component 3 in a reaction catalyzed by C3-convertase. There are three pathways of activation, each of which leads to the formation of C3a and C3b, which is involved in antigen opsonization. Other than the alternative pathway, which is constantly active, C3a formation is triggered by pathogenic infection. The classical pathway of complement activation is initiated when the C1 complex, made up of C… WebThe examples show the initial cleavage which removes C3a and C4a to produce C3b and C4b. An identical proteolytic cleavage pattern occurs for C3 and C4 with a hydrolyzed thioester bond (C3i and C4i) but the fragments still possess the C3a and C4a domains. The cofactors, not shown above, are MCP, factor H, or CR1 for C3 and MCP, C4BP, or CR1 …
