PF13377 | Periplasmic binding protein-like domain (Peripla_BP_3) | Periplasmic binding protein-like domain | This domain is found in a variety of transcriptional regulatory proteins. It is related to bacterial periplasmic binding proteins, although this domain is unlikely to be found in the periplasm. This domain acts as a sensor binding small molecule liga ... | Domain |
