| Popis: | Upon in vitro processing of the recombinant HIV-1/gag p24 protein, expressed in Escherichia coli as a fusion protein, by HIV-1 protease, a cleavage site within the staphylococcal protein A fusion partner was found. N-terminal sequencing of the protein A fragments showed that HIV-1 protease cleavage occurred between phenylalanine-235 and tyrosine-236 within the sequence Gln-Asn-Ala-Phe/Tyr-Glu-Ile-Leu (QNAF/YEIL) in the IgG-binding domain C of the protein A encoded by the pRIT2T fusion gene vector (Pharmacia). Results presented here have proven that the protease-sensitive site is viable in vitro on the protein A alone and other chimeric protein, protein A/β-galactosidase. A possible significance of this phenomenon in biotechnology work is discussed. |
