The PAS fold corresponds to the structural domain that has previously been defined as PAS and PAC motifs [4]. The PAS fold appears in archaea, eubacteria and eukarya. This domain is associated to signalling systems and works as a signal sensor domain. It recognises differently substituted aromatic hydrocarbons, oxygen, different dodecanoic acids, autoinducers, 3,5-dimethyl-pyrazin-2-ol and N-alanyl-aminoacetone (Matilla et. al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).
