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 pure samples with few steps of purification but also resulted in N-terminally free proteins. The extra purity of the samples was analyzed by reverse phase HPLC. Deglycosylation studies of CCP-25 with PNGase F enzyme revealed that its asparagine or asparagine-linked glycon contents are negligible. Partial N-terminal sequence of the CCP-25 showed the sequence (ANDIS), which seems to be conserved among plant antiviral proteins.
