===MAIN PORIN FROM MYCOBACTERIA SMEGMATIS (MSPA)===

~~==Overview==~~

<!--

~~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 consecutive beta barrels with nonpolar outer surfaces that form a ribbon around the porin~~, ~~which~~ is ~~too narrow to fit~~ the ~~thickness of the mycobacterial outer membrane in contemporary models~~.

The line below this paragraph, {{ABSTRACT_PUBMED_14976314}}, adds the Publication Abstract to the page

(as it appears on PubMed at http://www.pubmed.gov), where 14976314 is the PubMed ID number.
