The MntC crystal structure suggests that import of Mn2+ in cyanobacteria is redox controlled.

The MntC protein is the periplasmic solute-binding protein component of the high-affinity manganese ATP-binding cassette-type transport system in the cyanobacterium Synechocytis PCC sp. 6803. We have determined the structure of recombinant MntC at 2.

Preliminary X-ray crystallographic analysis of a soluble form of MntC, a periplasmic manganese-binding component of an ABC-type Mn transporter from Synechocystis sp. PCC 6803.

Manganese is recruited in microorganisms by way of ABC-type transporter systems. Here, the expression, purification and preliminary crystallographic analysis of a soluble form of the MntC solute-binding protein component of the MntABC manganese-import system from the cyanobacterium Synechococystis sp. PCC 6803 is reported.
