Architecture of the Cellulose Synthase Outer Membrane Channel and Its Association with the Periplasmic TPR Domain.
-
The E. coli BcsC C-terminal construct (residues 710-1157) resolves a 16-stranded outer-membrane barrel attached to the final TPR repeat; it supports homolog-based assignment of PP_2638 as the cellulose export channel.
"The membrane-integrated porin domain of BcsC forms a kidney-shaped 16-stranded β-barrel"
Insights into phosphoethanolamine cellulose synthesis and secretion across the Gram-negative cell envelope.
-
The E. coli BcsC N-terminal TPR region contacts the terminal BcsB of a periplasmic assembly; the detailed interface used a TPR/BcsB fusion.
"To improve the resolution of the BcsB-BcsC complex map, BcsC’s TPR#1–4 were fused to the N-terminus of BcsB"
Cell-cell and cell-surface interactions mediated by cellulose and a novel exopolysaccharide contribute to Pseudomonas putida biofilm formation and fitness under water-limiting conditions.
-
The abstract explicitly studies P. putida mt2. It reports a minor bcs contribution to biofilm stability and a contribution to rhizosphere colonization; these are operon-level phenotypes, not KT2440 target-protein assays.

OpenScientist gene research for PP_2638
-
OpenScientist identifies PP_2638/Q88JL1 as the BcsC outer-membrane cellulose secretion porin by domain architecture, operon context, and full-length similarity to characterized BcsC orthologs.
"PP_2638 is BcsC, the outer-membrane cellulose secretion porin."
