Evidence of isochorismate channeling between the Escherichia coli enterobactin biosynthetic enzymes EntC and EntB

Author(s): Bin X; Pawelek PD;

Enterobactin is a high-affinity iron chelator produced and secreted by Escherichia coli and Salmonella typhimurium to scavenge scarce extracellular Fe3+ as a micronutrient. EntC and EntB are the first two enzymes in the enterobactin biosynthetic pathway. Is ...

Evidence of an intracellular interaction between the Escherichia coli enzymes EntC and EntB and identification of a potential electrostatic channeling surface

Author(s): Ouellette S; Pakarian P; Bin X; Pawelek PD;

Siderophores are high-affinity small-molecule chelators employed by bacteria to acquire iron from the extracellular environment. The Gram-negative bacterium Escherichia coli synthesizes and secretes enterobactin, a tris-catechol siderophore. Enterobactin is ...

The stress induced caleosin, RD20/CLO3, acts as a negative regulator of GPA1 in Arabidopsis

Author(s): Brunetti SC; Arseneault MKM; Wright JA; Wang Z; Ehdaeivand MR; Lowden MJ; Rivoal J; Khalil HB; Garg G; Gulick PJ; ...

A stress induced calcium-binding protein, RD20/CLO3 interacts with the alpha subunit of the heterotrimeric G-protein complex in Arabidopsis and affects etiolation and leaf morphology. Heterotrimeri ...

Inter-protein residue covariation information unravels physically interacting protein dimers

Author(s): Salmanian S; Pezeshk H; Sadeghi M;

Background: Predicting physical interaction between proteins is one of the greatest challenges in computational biology. There are considerable various protein interactions and a huge number of protein sequences and synthetic peptides with unknown interacti ...
