Research Abstract

What is the function of many membrane proteins written in the genome of Vibrio? Which is the gene that code K+/H+antiporter function for internal pH regulation in Vibrio? Does internal Ca^<2+> concentration be maintained low? If so, what kind of transporter does the task. What kind of real functions of Pha system, NhaP2, Fku, Trk and Ktr in Vibrio cells? We looked forward such queries and found some answers.
