Research over the past decade has extended the prevailing view of the mitochondrion to
include functions well beyond the generation of cellular energy. It is now recognized that …

Porins form aqueous channels that aid the diffusion of small hydrophilic molecules across
the outer membrane of Gram-negative bacteria. The crystal structures of matrix porin and …

New textbooks at all levels of chemistry appear with great regularity. Some fields like basic

The integral membrane protein porin from Rhodobacter capsulatus consists of three tightly
associated 16-stranded β barrels that give rise to three distinct diffusion channels for small …

We report here, for the first time, the primary structure of uncoupling protein as established
by amino acid sequencing. Like the ADP/ATP carrier, this protein has a tripartite structure …
