RESUMO
Two new RNase inhibitors, SaI14 (Mr, ∼14,000) and SaI20 (Mr, ∼20,000), were isolated and purified from a Streptomyces aureofaciens strain. The gene sai14, coding for SaI14 protein, was cloned and expressed in Escherichia coli. The alignment of the deduced amino acid sequence of SaI14 with that of barstar, the RNase inhibitor from Bacillus amyloliquefaciens, showed significant similarity between them, especially in the region which contains most of the residues involved in barnase-barstar complex formation.
