Evolutionary changes in bacterial enzyme may speed up protein production
Researchers from Japan, Croatia and Switzerland report that evolutionary shifts in the isoleucyl-tRNA synthetase enzyme could help bacteria make proteins faster.
Study identifies three enzyme groups
Scientists traced the evolutionary history of the key protein synthesis enzyme known as isoleucyl-tRNA synthetase. They identified three distinct clades within this enzyme family during their analysis. The research team published these findings in the journal Nature Communications.
Structural changes affect reaction speed
The study suggests that C-terminal remodeling helped refine how quickly the enzyme works. Repeated loss of a structural region called INS appears to have improved reaction speed. These modifications allow the enzyme to match amino acids to their carriers more efficiently.
