The SLC4 family consists of 10 genes (SLC4A1–5; SLC4A7–11). All encode integral
membrane proteins with very similar hydropathy plots—consistent with 10–14 …

Cyanobacteria are photosynthetic bacteria with a unique CO2 concentrating mechanism
(CCM), enhancing carbon fixation. Understanding the CCM requires a systems level …

Bicarbonate transporters are regulated by signaling molecules/ions such as protein kinases,
ATP, and Ca2+. While phospholipids such as PIP2 can stimulate Na-H exchanger activity …

Betaine and Na+ symport has been extensively studied in the osmotically regulated
transporter BetP from Corynebacterium glutamicum, a member of the betaine/choline …

There is a clear relationship between the density of plasmalemmasomes (PLSs) in the acid
band regions of whorl cells of Chara corallina and the capacity of these cells to utilize …

COOH-terminal cytoplasmic tails of chloride/bicarbonate anion exchangers (AE) bind
cytosolic carbonic anhydrase II (CAII) to form a bicarbonate transport metabolon, a …

The apparent photosynthetic affinity of Anabaena variabilis for extracellular inorganic carbon
(Ci) was strikingly increased by Na+. The effect was highly specific for Na+ and was maximal …

The green marine macroalga Ulva lactuca L. was found to be able to utilize HCO3− from sea
water in two ways. When grown in flowing natural sea water at 16° C under constant dim …

Photosynthesis uses solar energy to drive inorganic carbon (Ci) uptake, fixation, and
biomass formation. In cyanobacteria, Ci uptake is assisted by carbon concentrating …

Aphanothece halophytica is a halotolerant alkaliphilic cyanobacterium which can grow in
media of up to 3.0 M NaCl and pH 11. This cyanobacterium can synthesize betaine from …
