Phoa protein
Webb26 feb. 2002 · An important first step in the characterization of an integral membrane protein of the helix bundle class is to determine its membrane topology—i.e., the number of transmembrane α-helices and the overall in/out orientation of the protein relative to the membrane.In Escherichia coli, this step is usually accomplished by using reporter … Webb17 dec. 2013 · In this report, we identify the co-translational protein targeting machinery, comprised of the Signal Recognition Particle (SRP; Ffh protein in complex with 4.5S RNA; Figure 2A) and the SRP Receptor (SR; FtsY), as a regulator of σ 32.
