Esterase D Is Essential for Protection of Neisseria gonorrhoeae against Nitrosative Stress and for Bacterial Growth during Interaction with Cervical Epithelial Cells
[摘要]:estD encodes a carboxylic ester hydrolase and is part of the NmlR regulon in Neisseria gonorrhoeae. An estD mutant was found to be susceptible to nitrite and to S-nitrosoglutathione. This mutant was also unable to infect and survive within human cervical epithelial cells, and it showed reduced ability to form a biofilm on these cells. We conclude that esterase D is an integral part of the nitrosative stress defense system of N. gonorrhoeae and that it has potential importance in pathogenesis.
