Understanding protein higher order structure and interfacial interactions is crucial to understanding protein binding motifs and cellular function, that is, an interactome. Polyubiquitylation is a post-translational modification that functions as a tag for a diverse array of cellular processes, wherein differences in chain length, branching, and linkage site encode different cellular functions....

Strains of enterotoxigenic Escherichia coli that produce 987P fimbriae (987P+ strains) colonize the small intestines and cause diarrhea in neonatal (< 6-day-old) pigs but not in weaned pigs. However, 987P+ E. coli strains adhere in vitro to intestinal epithelial cells from pigs of both ages. Two intestinal components, designated 987R and 987M, bind 987P fimbriae (987P) on Western blots (immunob...

as the main element of economy, human being has requirements the main one of which is the need for food security and healthy nutrition. unfortunately, in the iranian society there are two groups of people who do not enjoy food security. these groups include people who either do not have the financial means to provide healthy and nutritious food or those who, despite having the financial means, ...

Let A be the arrangement of hyperplanes consisting of the re ecting hyperplanes for the root system An 1. Let B = B(q) be the Varchenko matrix for this arrangement with all hyperplane parameters equal to q. We show that B is the matri x with rows and columns indexed by permutations with ; entry equal to qi( 1) where i( ) is the number of inversions of . Equivalently B is the matrix for left mul...
