摘要: A Vibrio tubiashii hemagglutinin, a protease, was purified by ammonium sulfate precipitation, gel filtration, and hydrophobic interaction chromatography. It agglutinates sheep, chicken, bovine, rabbit, guinea pig, human erythrocytes. has molecular mass of 35 kDa, isoelectric points 3.5 3.7, is inhibited ortho-phenanthro line, phosphoramidon, Zincov. The N-terminal amino acid sequence (Ala-Gln-Ala-Thr-Gly-Thr-Gly- Pro-Gly-Gly-Asn-Gln-Lys-Thr-Gly-Gln- Tyr-Asn-Phe-Gly) strong homology to other proteases.Key words: tubiashii, metalloprotease, hemagglutinin.
