Abstract:
The heptapeptide sequence Gly-Gly-Gly-Pro-Gly-Gly-Gly, when anchored to diglycolic acid derived (C18H37)2NCOCH2OCH2COOH, forms chloride-selective ion channels in phospholipid liposomes but the related heptapeptide Gly-Gly-Gly-Leu-Gly-Gly-Gly, and tripeptide Gly-Gly-Gly do not.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
