Role of C5a in inflammatory responses - PubMed
C5 convertase is an enzyme belonging to a family of serine proteases that play key role in the innate immunity. It participates in the complement system ending with cell death. There are four different C5 convertases able to specifically convert the protein C5 to C5a and C5b fragments. Two of the convertases are … See more Cell-bound C3 and C5 convertase differ in their C3b requirement. C3-convertase (C3bBb) need only one molecule of C3b to form, whereas two or more C3b are required for generation of C5 convertase (C3bBb). It means, … See more The target of C5 convertase is complement protein C5. C5 is a two-chain (α, β) plasma glycoprotein (Mr = 196,000). C5 and C3 have similar structure. However, C5 does not appear to contain the internal thiol ester group reported for C3 and C4.

Complement component 5a (C5a) is one of the most potent inflammatory proteins of the complement system. It results from the cleavage of the precursor protein C5 by the enzyme C5 convertases and binds to C5a receptor 1 (C5aR1 or CD88) (Ehrnthaller et al., 2011) and C5aR2 (C5a receptor-like two or C5L2), which are … C5a is a protein fragment released from cleavage of complement component C5 by protease C5-convertase into C5a and C5b fragments. C5b is important in late events of the complement cascade, an orderly series of reactions which coordinates several basic defense mechanisms, including formation of the membrane attack complex (MAC), one of the most basic weapons of the innat… how old in bang chan
