ComFB, a new widespread family of c-di-NMP receptor proteins

Sherihan Samir, Abdalla A. Elshereef, Vikram Alva, Jeanette Hahn, Frederik Eck, Louisa Celma, Eduardo Sabatine Lopes, Kai M. Thormann, David A. Dubnau, Michael Y. Galperin, Khaled A. Selim

The paper identifies ComFB as a new family of c-di-NMP receptors in bacteria, showing they bind c-di-GMP and c-di-AMP and regulate cellular processes like motility.

ComFB bound to c-di-GMP reduces swimming speed and tumbling frequency in B. subtilis

Jeanette Hahn, Roberto Noland, Louisa Celma, Abdalla El-shereef, Sherihan Samir, Eugenie Dubnau, Khaled A. Selim, Daniel B. Kearns, David A. Dubnau

The paper shows ComFB binds c-di-GMP to inhibit motility in B. subtilis by affecting flagellar activity, independent of MotI.
