Novel Organization and Divergent Dockerin Specificities in the Cellulosome System of Ruminococcus flavefaciens [PDF]
ABSTRACT The DNA sequence coding for putative cellulosomal scaffolding protein ScaA from the rumen cellulolytic anaerobe Ruminococcus flavefaciens 17 was completed. The mature protein exhibits a calculated molecular mass of 90,198 Da and comprises three cohesin domains, a C-terminal dockerin, and a unique ...

Ruminococcus bromii is a dominant member of the human gut microbiota that plays a key role in releasing energy from dietary starches that escape digestion by host enzymes via its exceptional activity against particulate “resistant” starches.

Adaptor Scaffoldins: An Original Strategy for Extended Designer Cellulosomes, Inspired from Nature
Designer cellulosomes consist of chimeric cohesin-bearing scaffoldins for the controlled incorporation of recombinant dockerin-containing enzymes. The largest designer cellulosome reported to date is a chimeric scaffoldin that contains 6 cohesins.

The Clostridium cellulolyticum Dockerin Displays a Dual Binding Mode for Its Cohesin Partner [PDF]
The plant cell wall degrading apparatus of anaerobic bacteria includes a large multienzyme complex termed the "cellulosome." The complex assembles through the interaction of enzyme-derived dockerin modules with the multiple cohesin modules of the noncatalytic scaffolding protein.

Cellulosome is a highly efficient multi-enzyme self-assembly system and is found on the extracellular surface or in the free environment of microorganisms. However, with a lack of Ca2+ in vivo, cellulosome assembly is challenging.

Mapping the deformability of natural and designed cellulosomes in solution
Background Natural cellulosome multi-enzyme complexes, their components, and engineered ‘designer cellulosomes’ (DCs) promise an efficient means of breaking down cellulosic substrates into valuable biofuel products.

Characterization and subcellular localization of the Clostridium thermocellum scaffoldin dockerin binding protein SdbA [PDF]
This article reports the characterization of the Clostridium thermocellum SdbA protein thought to anchor the cellulosome to the bacterial cell surface. The NH2-terminal region of SdbA consists of a cohesin domain which specifically binds the dockerin domain of the cellulosomal scaffolding protein CipA. The COOH-terminal region consists of a triplicated

CRISPR-PIN: Modifying gene position in the nucleus via dCas9-mediated tethering
Spatial organization of DNA within the nucleus is important for controlling DNA replication and repair, genetic recombination, and gene expression. Here, we present CRISPR-PIN, a CRISPR/dCas9-based tool that allows control of gene Position in the Nucleus
