An antiviral protein (25 kD) isolated from leaves of Celosia cristata (CCP 25) was tested for depurination study on ribosomal RNA from yeast. Ribosomal RNA yielded 360 nucleotide base fragment after treatment with CCP 25 indicating that CCP 25 was a ribosome inactivating protein. CCP 25 also
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
Plants antiviral proteins are being used as anticancer agents and inhibit other viral diseases in humans. We modified the purification protocol of the two N-terminally blocked antiviral glycoproteins, CCP-25 and CCP-27, purified from the leaves of Celosia cristata. This not only gave rise to single
A full-length cDNA clone, encoding a ribosome inactivating/antiviral protein (RIP/AVP) was isolated from the cDNA library of post-flowering stage of Celosia cristata leaves. The full-length cDNA consisted of 1015 nucleotides, with an open reading frame encoding 283 amino acids. The deduced amino
Considering Celosia plumosa as a potent antiviral plant, the attempt was made to determine, purify and characterize its proteinaceous antiviral elements against tobacco mosaic virus hypersensitive response on Nicotiana glutinosa. By using 60% ammonium sulphate-precipitation, FPLC-based
