Webb16 maj 2024 · PepT has twelve transmembrane (TM) helices that fold into an N-terminal domain (NTD, TM1-6) and a C-terminal domain (CTD, TM7-12) and has a large extracellular domain (ECD) between TM9-10. It is well recognized that peptide transport requires movements of the NTD and CTD, but the role of the ECD in PepT1 remains unclear. Webb13 maj 2015 · CodY and ScoC are Bacillus subtilis transcriptional regulators that control the expression of dozens of genes and operons.
