What is it about?
Sulfolobus is an obligate aerobe and chemoheterotroph that grows on a variety of carbon sources. In contrast to S. solfataricus, it has been reported that S. acidocaldarius cannot grow on maltose reflecting the more limited substrate utilization. We characterized the catalytic properties of MalA, one of the 7 genes (malA, trmB, amyA, malG, malF, malE, and malK) located in the maltose/maltodextrin transporter operon.

Why is it important?
Our findings show that the maltose/maltodextrin ABC transporter operon encoded by the saci_1160 to saci_1166 gene cluster is critical for starch or maltose utilization.
