A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.
A correlation between the periplasmic embellishment of the flagellar motor and its stator system type is described, motors with dual H+-dependent stator systems have one periplasmic ring formed by MotY.
The histone chaperone FACT and the deubiquitinating enzyme Ubp10 act in concert to remove ubiquitin from histone H2B in nucleosomes, and likely coordinate nucleosome assembly during DNA replication and transcription.
Genetic change among enzyme orthologous with similar phenotypic properties can cause substantial differences in evolutionary response to a new enzyme function in terms of their molecular and fitness outcomes.
The molecular microenvironment of coronaviral replicase complexes provides functional and spatial links between conserved cellular processes and viral RNA synthesis, and highlights potential targets for the development of novel antivirals.
In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.
