The meiotic recombination landscape in vertebrates was re-engineered via the co-evolution of a dual histone H3K4/H3K36 methylation 'writer' PRDM9 and its 'reader' ZCWPW1 that facilitates efficient double strand break repair.
A new method of protein structure prediction that incorporates residue–residue co-evolution information into the Rosetta structure prediction program was used to develop models for 58 large protein families that had no previous structural information.
The phosphate starvation response network in a commensal yeast evolved to expand its downstream targets via changes in the main transcription factor's dependence on its co-activator, potentially altering the physiological response.
HIV co-infection does not affect Mycobacterium tuberculosis mutation rates and does not drive the emergence of antimicrobial resistance within patients in the largest outbreak of multidrug-resistant tuberculosis in Latin America to date.
Evolutionary bioinformatics and experimentation are applied to the components of the Tat protein transport system to elucidate the structure of the membrane-bound receptor complex and to deduce a molecular description for its substrate-triggered activation.
Hairless emerged as an evolutionarily novel regulatory protein that replaced an ancestral paradigm of direct co-repressor recruitment by Suppressor of Hairless, its partner transcription factor in the Notch signaling pathway.
