Structural and functional proteomics of intracytoplasmic membrane assembly in Rhodobacter sphaeroides.
United States. In J Mol Microbiol Biotechnol, 2012
Functional aspects of the photosynthetic unit assembly process were monitored by fluorescence induction/relaxation measurements of the variable fluorescence arising from LH-bacteriochlorophyll a. Slowing of the rate of RC electron transfer turnover (τQA), as assessed from the relaxation phase, was correlated with the growth of the functional absorption cross section (σ) and LH2/LH1 molar ratios.
The medial habenula: still neglected.
Houston, United States. In Front Hum Neurosci, 2012
While the lateral habenula (LHb) has been extensively studied, the anatomically and histochemically distinct medial habenula (MHb) remains largely understudied.
Luteinizing hormone beta mutation and hypogonadism in men and women.
Brasília, Brazil. In N Engl J Med, 2007
homozygous mutation of a 5' splice site in LHB: IVS2+1G-->C disrupts the splicing of messenger RNA, generating a gross abnormality in the processing of the luteinizing hormone beta-subunit mRNA, which abrogates the secretion of luteinizing hormone
The native architecture of a photosynthetic membrane.
Enschede, Netherlands. In Nature, 2004
In the first, groups of 10-20 molecules of LH2 form light-capture domains that interconnect linear arrays of dimers of core reaction centre (RC)-light-harvesting 1 (RC-LH1-PufX) complexes; in the second they were found outside these arrays in larger clusters.
Crystal structure of the RC-LH1 core complex from Rhodopseudomonas palustris.
Glasgow, United Kingdom. In Science, 2004
The crystal structure at 4.8 angstrom resolution of the reaction center-light harvesting 1 (RC-LH1) core complex from Rhodopseudomonas palustris shows the reaction center surrounded by an oval LH1 complex that consists of 15 pairs of transmembrane helical alpha- and beta-apoproteins and their coordinated bacteriochlorophylls. Complete closure of the RC by the LH1 is prevented by a single transmembrane helix, out of register with the array of inner LH1 alpha-apoproteins.
