It is well established that cecropins have the ability to adopt amphipathic alpha-helices, which is thought to be required for their bactericidal activity.

A comparative study on the structure and function of a cytolytic alpha-helical peptide and its antimicrobial beta-sheet diastereomer.

290, 99–117 (1999). In the video I say amphipathic as a In this video I talk about the alpha helix and solve a multistep problem that provides some insight into the alpha helix. N-terminal 39 amino acids (2C 40–329) or the amphipathic -helix only (2C D17–38) resulted in a loss of association with LDs. Conversely, the ﬁrst 38 amino acids with the helix are sucient to be associated with LDs, suggesting that the helix plays an essential role in targeting 2C to its destination Amphipathic alpha helices. This model corresponds to a 19 amino acid residue stretch with alpha helix secondary structure. (Specifically, it is helix E of the beta subunit of human haemoglobin.)

Department of Medicine, UAB Medical Center, Birmingham, Alabama 35294. Department of Biochemistry, UAB Medical Center, Birmingham, Alabama 35294 Amphipathic a-helix: The amphipathic helix motif is characterized by a repeating pattern of polar (P) and non-polar (N) sidechains that can be summarized as PxNPPNx. These clusters varied in length from 6 to 15 residues, the longer ones being the best predictors. 2009-03-27 · A putative amphipathic α-helix in BMV 1a is sufficient for membrane association Previously, using membrane affinity and protease sensitivity assays, we showed that BMV 1a strongly localizes to the cytoplasmic face of the ER membrane despite lacking any detectable trans-membrane domain. It is important to mention, that this α‐helix comprises the conserved θ 1 xxθ 2 xxθ 3 motif and has amphipathic character with residues Leu ‐17 (θ 1), Leu ‐14 (θ 2), Leu ‐11 (θ 3) and residues Glu ‐16, Glu ‐13 and Asp ‐10 representing the hydrophobic and negatively‐charged patches of the α‐helix, respectively (Figure 4 b and S3). 2007-01-14 · An amphipathic alpha-helix at a membrane interface: a structural study using a novel X-ray diffraction method.

O monolayer associated membrane protein O lipid-linked membrane protein O transmembrane protein O protein-attached membrane protein Helixator - creates a helical wheel plot that displays a protein sequence looking down the axis of the alpha helix. This view facilitates the identification of amphipathic TMSs. HMMTOP - Highlight TMS regions in a protein as predicted by HMMTOP TMSTATS - Statistical analysis of topological data within any TC hierarchy, domain, or phyla This activates the Sar1 protein, causing its amphipathic alpha helix to bind to the ER membrane. Membrane bound Sar1 attracts the Sec23-Sec24 protein heterodimer to the ER membrane. Sar1 directly binds to Sec23 while Sec24 directly binds to the cargo receptor located on the ER membrane. An amphipathic alpha helix has a hydrophobic face and a hydrophilic face owing to the arrangement of hydrophobic and hydrophilic side chains in the sequential amino acids.
