PMID: 15618721
Drug Metab Pharmacokinet. 2003;18(1):79-85. doi: 10.2133/dmpk.18.79.

The effects of the substitution of glycine at position 42 with various other amino acid residues on the functions of CYP2D6 were studied using debrisoquine (DB) and bunitrolol (BTL) 4-hydroxylations as indices of drug-metabolizing enzymes. The substitution with hydrophobic...

Mutants of Sweetclover (Melilotus alba) Lacking Chlorophyll b: Studies on Pigment-Protein Complexes and Thylakoid Protein Phosphorylation.

Plant physiology

Markwell JP, Webber AN, Lake B.
PMID: 16664169
Plant Physiol. 1985 Apr;77(4):948-51. doi: 10.1104/pp.77.4.948.

Mutants of sweetclover (Melilotus alba) with defects in the nuclear ch5 locus were examined. Using thin-layer chromatography and absorption spectroscopy, three of these mutants were found to lack chlorophyll (Chl) b. One of these three mutants, U374, possessed thylakoid...

Chemical Cross-linking of Neighboring Thylakoid Membrane Polypeptides.

PMID: 16660519
Plant Physiol. 1978 Sep;62(3):368-72. doi: 10.1104/pp.62.3.368.

Cross-linking between protein components of whole spinach (Spinacia oleracea var. Nobel) thylakoids and of photosystem I- and II-enriched thylakoid fractions has been produced by reaction with the bifunctional imidoester dimethyl-3,3'-dithiobispropionimidate dihydrochloride as well as by the oxidation of intrinsic...

Protein domains required for formation of stable monomeric Lhca1- and Lhca4-complexes.

Photosynthesis research

PMID: 16228432
Photosynth Res. 2000;63(3):217-24. doi: 10.1023/A:1006499517613.

The peripheral light-harvesting complex of Photosystem I consists of two subpopulations, LHCI-680 and LHCI-730. The latter is composed of the two apoproteins Lhca1 and Lhca4. Recently, reconstitution of monomeric LHCI using bacterially overexpressed Lhca1 or Lhca4 was achieved. In...

Antisense inhibition of the beta-carotene hydroxylase enzyme in Arabidopsis and the implications for carotenoid accumulation, photoprotection and antenna assembly.

Photosynthesis research

Rissler HM, Pogson BJ.
PMID: 16228322
Photosynth Res. 2001;67(1):127-37. doi: 10.1023/A:1010669404183.

The xanthophylls are oxygenated carotenoids and are important structural components of the photosynthetic apparatus. Xanthophylls contribute to the assembly and stability of light-harvesting complex apoproteins (LHC) and contribute to photoprotection via non-photochemical quenching of chlorophyll fluorescence (NPQ) in oxygenic...

Transcription of three sets of genes coding for the core light-harvesting proteins in the purple sulfur bacterium, Allochromatium vinosum.

Photosynthesis research

Nagashima S, Shimada K, Matsuura K, Nagashima KV.
PMID: 16245138
Photosynth Res. 2002;74(3):269-80. doi: 10.1023/A:1021280104053.

The nucleotide sequence of the puf operon coding for the subunits of the photosynthetic reaction center and the core light-harvesting complex (LH1) of the purple sulfur bacterium, Allochromatium (A.) vinosum (formally Chromatium vinosum), was completely determined. Unlike other known...

Species-related differences in the electrophoretic behavior of CP 29 and CP 26: An immunochemical analysis.

Photosynthesis research

Falbel TG, Staehelin LA.
PMID: 24408776
Photosynth Res. 1992 Nov;34(2):249-62. doi: 10.1007/BF00033442.

The monomeric chlorophyll-protein complexes, CP 29 and CP 26 seen in the Camm and Green (1980) and Dunahay and Staehelin (1986) green gels do not always migrate in the order of the apparent molecular weight of their apoproteins as...

The localization of genes for ribosomal, cytochrome b6/f complex and photosystems I and II polypeptides on the chloroplast chromosome of Vicia faba.

Plant molecular biology

Ko K, Straus NA.
PMID: 24302308
Plant Mol Biol. 1986 May;7(3):219-28. doi: 10.1007/BF00021334.

Detailed studies of rearranged chloroplast genomes such as Vicia faba should give insights into the constraints governing the positional organization of the various gene clusters on the chloroplast chromosome. Seven polypeptide genes have already been mapped on the Vicia...

Synthesis and turnover of the light-harvesting chlorophylla/b-protein inLemna gibba grown with intermittent red light: possible translational control.

Lemna gibba L. G-3 plants grown heterotrophically in the dark with intermittent red light (2 min every 8 h) contain a substantial amount of translatable mRNA encoding the light-harvesting chlorophyll (Chl)a/b-protein. However, very little [(35)S]methionine is incorporated into the...
