Topological model of the Rhodobacter capsulatus light-harvesting complex I assembly protein LhaA (previously known as ORF1696)

Abstract

A theoretical topology of the Rhodobacter capsulatus membrane protein LhaA was formulated and evaluated by gene fusion experiments. The apparent topological locations of fusion enzymes were compared with the theoretically derived structure, and a model of LhaA is suggested that consists of 12 transmembrane segments, with the N and C termini residing in the cytoplasm.
