Functional and structural insights into cyanobacterial CO2 concentrating mechanisms: from compartmentalization to regulation

The Plant Journal, Volume 126, Issue 5, June 2026.
Significance Statement Life on Earth depends on photosynthetic CO2 fixation via the Calvin–Benson–Bassham cycle to form organic carbon. This process evolved first in cyanobacteria and was later conveyed to eukaryotes, giving rise to plastids in algae and plants. To cope with low atmospheric CO2 concentrations that developed over the course of evolution,

Sodium Iodide Symporter (NIS) and Thyroid

HORMONES, 2002
idase (TPO) and incorporation into tyrosyl residues along the thyroglobulin (Tg) backbone. The thyroid hormones T3 and T4 are synthesized by coupling of two iodotyrosine residues and stored in the colloid. All of these steps are stimulated by pituitary-derived thyroid stimulating hormone (TSH), which interacts with the TSH receptor at the basolateral ...

Alternate Modes of Photosynthate Transport in the Alternating Generations of Physcomitrella patens

Frontiers in Plant Science, 2017
Physcomitrella patens has emerged as a model moss system to investigate the evolution of various plant characters in early land plant lineages. Yet, there is merely a disparate body of ultrastructural and physiological evidence from other mosses to draw ...

MFS transportome of the human pathogenic yeast Candida albicans

BMC Genomics, 2008
Background The major facilitator superfamily (MFS) is one of the two largest superfamilies of membrane transporters present ubiquitously in bacteria, archaea, and eukarya and includes members that function as uniporters, symporters or antiporters.

The C-terminus of the multi-drug efflux pump EmrE prevents proton leak by gating transport

eLife
The model multi-drug efflux pump from Escherichia coli, EmrE, can perform multiple types of transport leading to different biological outcomes, conferring resistance to some drug substrates and enhancing susceptibility to others.

Salinity-Dependent Shift in the Localization of Three Peptide Transporters along the Intestine of the Mozambique Tilapia (Oreochromis mossambicus)

Frontiers in Physiology, 2017
The peptide transporter (PepT) systems are well-known for their importance to protein absorption in all vertebrate species. These symporters use H+ gradient at the apical membrane of the intestinal epithelial cells to mediate the absorption of small ...

Complex evolution of the DAL5 transporter family

BMC Genomics, 2008
Background Genes continuously duplicate and the duplicated copies remain in the genome or get deleted. The DAL5 subfamily of transmembrane transporter genes has eight known members in S. cerevisiae.

Phaseolus vulgaris STP13.1 is an H+‐coupled monosaccharide transporter, present in source leaves and seed coats, with higher substrate affinity at depolarized potentials

Plant Direct
Sugar transport proteins (STPs) are high‐affinity H+‐coupled hexose symporters. Recently, the contribution of STP13 to bacterial and fungal pathogen resistance across multiple plant species has garnered significant interest.
