Assembly of Xylanases into Designer Cellulosomes Promotes Efficient Hydrolysis of the Xylan Component of a Natural Recalcitrant Cellulosic Substrate

mBio, 2011
In nature, the complex composition and structure of the plant cell wall pose a barrier to enzymatic degradation. Nevertheless, some anaerobic bacteria have evolved for this purpose an intriguing, highly efficient multienzyme complex, the cellulosome ...

Predicting Selective RNA Processing and Stabilization Operons in Clostridium spp.

Frontiers in Microbiology, 2021
In selective RNA processing and stabilization (SRPS) operons, stem–loops (SLs) located at the 3′-UTR region of selected genes can control the stability of the corresponding transcripts and determine the stoichiometry of the operon. Here, for such operons,

In vivo Functional Characterization of Hydrophilic X2 Modules in the Cellulosomal Scaffolding Protein

Frontiers in Microbiology, 2022
As part of free cellulases or scaffolding proteins in cellulosomes, the hydrophilic non-catalytic X2 module is widely distributed in cellulolytic Clostridia or other Firmicutes bacteria. Previous biochemical studies suggest that X2 modules might increase

Cellulosome components of C. thermocellum.

, 2014
Enzymatic components (colored differently to indicate enzyme variety) produced by anaerobic bacteria contain a dockerin domain. Dockerins bind the cohesins of a non-catalytic scaffoldin, providing a mechanism for cellulosome assembly.

The cellulosome of Clostridium cellulolyticum

, 2005
Clostridium cellulolyticum ATCC 35319 has been extensively studied in the past few years on both the enzymatic and metabolic aspects of cellulose degradation and is considered as the model of mesophilic cellulolytic clostridia.
