Thermaceae is a family of bacteria belonging to the phylum Deinococcota.

[1] They are particularly resistant to heat, and live in the benthic zone of the Gulf of Mexico.

Specifically, six CSIs were identified in the following proteins: DNA topoisomerase I, ABC transporter permease, citrate synthase, phosphoribosylformylglycinamidine synthase, pyruvate dehydrogenase and alpha-glucan phosphorylase.

[3] 51 CSPs were also found to be exclusively shared by members of this order.

[3] In addition, a 76 aa CSI is present in the protein SecA preprotein translocase which is specific to all members of the order Thermales as well as Hydrogenibacillus schlegelii (also an thermophilic species).
