Regulation summary diagram for yfiN

YfiN is a predicted diguanylate cyclase and an inner membrane protein with two predicted transmembrane domains. The C terminus is located in the cytoplasm [Daley05].

Deletion of yfiN partially restores motility of a yhjH mutant, suggesting that YfiN is one of four diguanylate cyclases that adjust c-di-GMP concentration for motility control [Boehm10]. Deletion of yfiN also suppresses the swarming defect of a yfiR deletion mutant [Girgis07]. A yfiN deletion mutant shows 18-fold increased early biofilm formation and 10-fold increased swimming motility. Deletion of yfiN does not alter the concentration of c-di-GMP inside the cell [SanchezTorres11].

In uropathogenic E. coli UTI89, YfiN encodes a diguanylate cyclase that contributes to a cellulose production pathway. YfiN is is repressed by the periplasmic protein YfiR [Hufnagel14]. yfiR, yfiN and yfiB may form an operon in E. coli K-12. In Pseudomonas aeruginosa this operon is involved in exopolysaccharide synthesis [Malone10]; in uropathogenic E. coli YfiR and YfiN were shown to have a role in cellulose production but no evidence implicating YfiB in this process was obtained [Hufnagel14]. E. coli K-12 does not produce cellulose due to a mutation in the bcs operon (see cellulose biosynthesis protein, pseudogene lacking N-terminal amino acids).
