Author Correction Published: Structural Details of Light-Driven proton Pump heliorhodopsin Confirmed
A correction to a recently published study clarifies andโ confirms the crystal structure of heliorhodopsin,โ a light-sensitive protein crucial to โคunderstanding microbialโค life and potential bio-inspired technologies. The โupdated findings, published by an international team of โฃresearchers, refine the understanding of this proton pumpS mechanism and offer a more โprecise blueprint for future investigations.
Heliorhodopsin, discovered in 2017 in the haloarchaeon Halorubrum lacusprofundi, functions as a light-driven proton pump, converting lightโ energy into an electrochemical gradient. This process is essential to โขenergy production in many โคmicroorganisms and has sparked interest in its potential applications in areas like solar energy conversion and optogenetics.โ The initial structural determination faced challenges due to the โprotein’sโค inherent flexibility and โthe difficulty inโ obtaining high-quality crystals. โThis author correction addresses those challenges, providing a more โrobustโค and accurate structural model.
