Iron physiology and metabolism of model phytoplankton taxa in a western boundary continental shelf ecosystem

Limnology and Oceanography, Volume 70, Issue 11, Page 3335-3354, November 2025.
Abstract Continental shelf ecosystems support diverse phytoplankton communities that contribute to global primary productivity. Iron is an important micronutrient controlling the growth of marine phytoplankton, but its role in influencing phytoplankton ecophysiology in western boundary continental shelf ecosystems is understudied.

Engineering of soluble bacteriorhodopsin

Chemical Science
Analogues of membrane protein bacteriorhodopsin are reported that are soluble and stable, bind retinal and exhibit photocycles under illumination, highlighting the power of modern protein engineering approaches.

Excited-state dynamics of bacteriorhodopsin

Biophysical Journal, 1985
Near infrared emission of bacteriorhodopsin at neutral pH and at room temperature was characterized by a large Stokes shift. This characteristic was lost in an acidic pH (approximately pH 2) where a remarkable enchancement (more than 10 times) in the fluorescence quantum yield accompanied the red shift in the main absorption band.

Analogies between halorhodopsin and bacteriorhodopsin

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2000
The light-activated proton-pumping bacteriorhodopsin and chloride ion-pumping halorhodopsin are compared. They belong to the family of retinal proteins, with 25% amino acid sequence homology. Both proteins have seven alpha helices across the membrane, surrounding the retinal binding pocket. Photoexcitation of all-trans retinal leads to ion transporting
