A Map of Dielectric Heterogeneity in a Membrane Protein: the Hetero-Oligomeric Cytochrome b6f Complex
The cytochrome b6f complex, a member of the cytochrome bc family that mediates energy transduction in photosynthetic and respiratory membranes, is a hetero-oligomeric complex that utilizes two pairs of b-hemes in a symmetric dimer to accomplish trans-membrane electron transfer, quinone oxidation-reduction, and generation of a proton electrochemical potential. Analysis of electron storage in thi...
متن کاملSubunit organization of a synechocystis hetero-oligomeric thylakoid FtsH complex involved in photosystem II repair.
FtsH metalloproteases are key components of the photosystem II (PSII) repair cycle, which operates to maintain photosynthetic activity in the light. Despite their physiological importance, the structure and subunit composition of thylakoid FtsH complexes remain uncertain. Mutagenesis has previously revealed that the four FtsH homologs encoded by the cyanobacterium Synechocystis sp PCC 6803 are ...
متن کاملHetero-oligomeric assembly of P2X receptor subunits. Specificities exist with regard to possible partners.
P2X receptors are a distinct family of ligand-gated ion channels activated by extracellular ATP. Each of the seven identified subunit proteins (P2X1 through P2X7) has been reported to form functional homo-oligomeric channels when expressed in heterologous systems. Functional studies of native receptors, together with patterns of subunit gene expression, suggest that hetero-oligomeric assembly a...
متن کاملThe -Barrel Outer Membrane Protein Assembly Complex of Neisseria meningitidis
The evolutionarily conserved protein Omp85 is required for outer membrane protein (OMP) assembly in gram-negative bacteria and in mitochondria. Its Escherichia coli homolog, designated BamA, functions with four accessory lipoproteins, BamB, BamC, BamD, and BamE, together forming the -barrel assembly machinery (Bam). Here, we addressed the composition of this machinery and the function of its co...
متن کاملThermodynamic competition between membrane protein oligomeric states
Self-assembly of protein monomers into distinct membrane protein oligomers provides a general mechanism for diversity in the molecular architectures, and resulting biological functions, of membrane proteins. We develop a general physical framework describing the thermodynamic competition between different oligomeric states of membrane proteins. Using the mechanosensitive channel of large conduc...
