The Structure of a Mycobacterial Outer-Membrane Channel
@article{Faller2004TheSO, title={The Structure of a Mycobacterial Outer-Membrane Channel}, author={M. Faller and M. Niederweis and G. Schulz}, journal={Science}, year={2004}, volume={303}, pages={1189 - 1192} }
Mycobacteria have low-permeability outer membranes that render them resistant to most antibiotics. Hydrophilic nutrients can enter by way of transmembrane-channel proteins called porins. An x-ray analysis of the main porin from Mycobacterium smegmatis, MspA, revealed a homooctameric goblet-like conformation with a single central channel. This is the first structure of a mycobacterial outer-membrane protein. No structure-related protein was found in the Protein Data Bank. MspA contains two… CONTINUE READING
