Abstract

Leptospirosis is a zoonosis that has been highlighted by the high incidence rate in Brazil, mainly in regions devoid of sanitation. Understanding the biochemical mechanisms involved with this bacteria metabolism is of great importance to advance the understanding of the disease. This project seeks to analyze the structure and function of the proteins LIC13137 and LIC13000, which have a GGDEF domain, responsible for the production of a bacterial second messenger, c-di-GMP. Currently, we have cloned LIC11300 and LIC13137 different fragments in order to increase chances of obtaining well reeled proteins to make crystallization assays. We have expressed and obtained GAF domain crystals of LIC13137 and we are focused also on obtaining clones of the entire LIC13137 protein to analyze GAF domain effect on the activity of the GGDEF domain.
