Functional characterization of a novel xylanase from a corn strain of Erwinia chrysanthemi.

abstract：:Proteins of the YidC/OxaI/Alb3 family play a crucial role in the insertion, folding, and/or assembly of membrane proteins in prokaryotes and eukaryotes. Bacillus subtilis has two YidC-like proteins, denoted SpoIIIJ and YqjG. SpoIIIJ and YqjG are largely exchangeable in function, but SpoIIIJ has a unique role in sporul...
