Allosteric regulation accompanied by oligomeric state changes of Trypanosoma brucei GMP reductase through cystathionine-β-synthase domain

open access: yesNature Communications, 2020
Trypanosoma brucei guanosine 5′-monophosphate reductase (TbGMPR) catalyses the conversion of GMP to inosine 5′-monophosphate and contains a cystathionine-β-synthase (CBS) domain. Here the authors combine X-ray crystallography and kinetic measurements and

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
