In hyperthermophilic archaea there is a SKTPCX(2-3)C motif at the C-terminus. The cysteines in this motif form a disulphide bridge, which stabilises the protein [4].	Domain

This family consists of several Toluene-4-monooxygenase system protein B (TmoB) sequences. Pseudomonas mendocina KR1 metabolises toluene as a carbon source. The initial step of the pathway is hydroxylation of toluene to form p-cresol by a multicomponent toluene-4-monooxygenase (T4MO) system [1]. TmoB adopts a ubiquitin fold [2]. Although TmoB is a component of the T4MO system, its precise role remains unclear.	Domain
