The PECACE domain: a new family of enzymes with potential peptidoglycan cleavage activity in Gram-positive bacteria

BMC Genomics, 2005
Background The metabolism of bacterial peptidoglycan is a dynamic process, synthases and cleavage enzymes are functionally coordinated. Lytic Transglycosylase enzymes (LT) are part of multienzyme complexes which regulate bacterial division and elongation.

Adaptor Scaffoldins: An Original Strategy for Extended Designer Cellulosomes, Inspired from Nature

mBio, 2016
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.

Transiently Transfected Purine Biosynthetic Enzymes Form Stress Bodies [PDF]

, 2013
It has been hypothesized that components of enzymatic pathways might organize into intracellular assemblies to improve their catalytic efficiency or lead to coordinate regulation.

Deconstruction by C. thermocellum —from microbe mediated to dynamic redistribution of cellulosomes

Life Science Alliance
By combining super-resolution imaging and machine learning to study the dynamics of biomass deconstruction by C. thermocellum , we show that this deconstruction goes from a microbe-mediated strategy to a dynamic redistribution of cellulosomes during ...

Deconstruction of Lignocellulose into Soluble Sugars by Native and Designer Cellulosomes

mBio, 2012
Lignocellulosic biomass, the most abundant polymer on Earth, is typically composed of three major constituents: cellulose, hemicellulose, and lignin. The crystallinity of cellulose, hydrophobicity of lignin, and encapsulation of cellulose by the lignin ...

Repression of the auxin response pathway increases Arabidopsis susceptibility to necrotrophic fungi

, 2008
In plants, resistance to necrotrophic pathogens depends on the interplay between different hormone systems, such as those regulated by salicylic acid (SA), jasmonic acid (JA), ethylene, and abscisic acid.
