Azotobacter vinelandii AmrZ is a global regulator linking alginate production and c-di-GMP homeostasis

Miriam Citlalli Gonzaga-Pérez, Carlos Leonel Ahumada-Manuel, Ana Isabel Chávez-Martínez…·Cinthia E. Núñez

This paper identifies AmrZ as a global regulator in Azotobacter vinelandii that links alginate production to c-di-GMP homeostasis by directly activating algD and specific DGCs, while reducing motility.

The c-di-GMP effector FleQ controls alginate production by repressing transcription of the algD gene in Azotobacter vinelandii

Víctor V. Barrios-Rafael, Carlos Leonel Ahumada-Manuel, Scherezada Orgaz-Ramírez…·Cinthia E. Núñez

This study shows that FleQ, a c-di-GMP effector, represses algD transcription, controlling alginate production in Azotobacter vinelandii.
