The high-affinity maltose/trehalose ABC transporter in the extremely thermophilic bacterium Thermus thermophilus HB27 also recognizes sucrose and palatinose.

Abstract excerpt

We have studied the transport of trehalose and maltose in the thernophilic bacterium Thermus thermophilus HB27, which grows optimally in the range of 70 to 75 degrees C. The K(m) values at 70 degrees C were 109 nM for trehalose and 114 nM for maltose; also, a high K(m) (424 nM) was found for the uptake of sucrose. Competition studies showed that a single transporter recognizes trehalose, maltose, and sucrose,...
