An antiviral protein named CCP-27 was purified from the leaves of Celosia cristata at the post-flowering stage by anion-exchange, cation-exchange, and gel-filtration chromatography. It exhibited resistance against sunnhemp rosette virus in its test host Cyamopsis tetragonoloba. It also exhibited deoxyribonuclease activity against supercoiled pBlueScript SK+ plasmid DNA. It was found to nick supercoiled DNA into nicked circular form at lower protein concentration followed by nicked to linear form conversion at higher protein concentration. CCP-27 also possesses strong ribonuclease activity against Torula yeast rRNA.
