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, Josefina Guzmán, Karel Estrada, Guadalupe Espı́n, 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.
