Comparative genomics of bacterial and plant folate synthesis and salvage: predictions and validations [PDF]
Background Folate synthesis and salvage pathways are relatively well known from classical biochemistry and genetics but they have not been subjected to comparative genomic analysis.

GDP-to-GTP exchange on the microtubule end can contribute to the frequency of catastrophe
Microtubules are dynamic polymers of αβ-tubulin that have essential roles in chromosome segregation and organizing the cytoplasm. Catastrophe – the switch from growing to shrinking – occurs when a microtubule loses its stabilizing GTP cap.

Comprehensive analysis of the HEPN superfamily: identification of novel roles in intra-genomic conflicts, defense, pathogenesis and RNA processing [PDF]
BACKGROUND: The major role of enzymatic toxins that target nucleic acids in biological conflicts at all levels has become increasingly apparent thanks in large part to the advances of comparative genomics.

The catalytic domains of thiamine triphosphatase and CyaB-like adenylyl cyclase define a novel superfamily of domains that bind organic phosphates [PDF]
BACKGROUND: The CyaB protein from Aeromonas hydrophila has been shown to possess adenylyl cyclase activity. While orthologs of this enzyme have been found in some bacteria and archaea, it shows no detectable relationship to the classical nucleotide ...

Activation of GTP hydrolysis in mRNA-tRNA translocation by elongation factor G
Cryo-EM study reveals key molecular structural features for activation of guanosine triphosphate cleavage by EF-G during translocation. During protein synthesis, elongation of the polypeptide chain by each amino acid is followed by a translocation step ...
