SbtA is a high-affinity, sodium-dependent bicarbonate transporter found in the
cyanobacterial CO2-concentrating mechanism (CCM). SbtA forms a complex with SbtB …

Dear Editor, Carbon and nitrogen, the uptake and intracellular metabolisms of which are
tightly coupled 1, are the two most fundamental nutrients for all living organisms. As one of …

The transporter SbtA is a high affinity Na+-dependent HCO3-uptake system present in a
majority of cyanobacterial clades. It functions in conjunction with CO2 uptake systems and …

Cyanobacterial HCO3-transporters BCT1, SbtA and BicA are important components of
cyanobacterial CO2-concentration mechanisms. They also show potential in applications …

Bicarbonate transporters play essential roles in pH homeostasis in mammals and
photosynthesis in aquatic photoautotrophs. A number of bicarbonate transporters have been …

Cyanobacteria have evolved a suite of enzymes and inorganic carbon (Ci) transporters that
improve photosynthetic performance by increasing the localized concentration of CO2 …

The cyanobacterium Synechocystis sp. strain PCC 6803 possesses two CO 2 uptake
systems and two HCO 3− transporters. We transformed a mutant impaired in CO 2 uptake …

The PII superfamily consists of widespread signal transduction proteins found in all domains
of life. In addition to canonical PII proteins involved in C/N sensing, structurally similar PII …

Cyanobacteria, blue-green algae, are the most abundant autotrophs in aquatic
environments and form the base of the food chain by fixing carbon and nitrogen into cellular …

The cmpABCD operon of the cyanobacterium Synechococcus sp. strain PCC7942, which is
transcribed specifically under CO2-limited growth conditions, encodes an ATP-binding …
