The structure of the recombination complex responsible for flagellar antigen switching in Salmonella enterica, and the mechanism that regulates the site-specific DNA inversion reaction, have been determined.
Endoplasmic reticulum proteostasis factors enhance the mutational tolerance of influenza hemagglutinin, a model secretory pathway protein and therapeutic target, particularly improving the fitness of temperature-sensitive variants.
Increased mass enhances speed but compromises turning capacity in pursuit predators; this has widespread ramifications for the best strategies for predators and prey during chases according to their relative masses.
Plasmodium falciparum invasion protein EBA-175, once shed from the parasite surface post invasion, facilitates RBC clustering and enhances parasite growth while simultaneously enabling parasite immune evasion of host neutralizing antibodies.
Cardiac-specific overexpression of a recently discovered micropeptide, DWORF, enhances calcium cycling and contractility in the heart and rescues the heart failure phenotype of a genetic mouse model of dilated cardiomyopathy.
