Abstract:
:Human complement components C6 and C7 have been purified and characterized. Component C6 is a single-chain plasma protein of mol. wt 104,800 containing 3.8% carbohydrate and it has alanine as the amino terminal residue. Component C7 is a single-chain plasma protein of mol. wt 92,400 containing 6.4% carbohydrate and it has serine as the amino terminal residue. Primary sequence analysis failed to provide evidence of homology between these two proteins.
