including a novel four-transmembrane-helix Lhca. In total, 244 chlorophylls were identified, some of which were located at key positions for the fast energy transfer. These results provide a firm structural basis for unravelling the mechanisms of light-energy harvesting, transfer and quenching in ...
total nitrogen, total phosphorus, ammonia, high manganese on permanganate index, chemical oxygen demand, fluoride, biological oxygen demand, nitrate, nitrite, phosphate solubility and chlorophyll a) were monthly investigated at seven sites in Taihu Lake between January and December of 2013 in our study...
Although it is unlikely that the structure corresponds to the catalytically active conformation of the enzyme, it represents a novel nucleic acid fold with implications for the Holliday junction structure. 展开 关键词: chlorophyll fluorescence oxidative stress DOI: 10.1038/5839 被引量: 350 ...
Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis. Chloroplasts are a type of plastid that are distinguished by their green color, the result of specialized chlorophyll pigments. In plants, chloroplasts

Plankton response to El Nio 1997–1998 and La Nia 1999 in the southern region of the California Current We present results of chlorophyll a concentrations and zooplankton displacement volumes for the eight cruises from September 1997 to October 1999. The ... B.E Lavaniegos a b,L.C Jiménez-...
Earlier we have shown by in vitro reconstitution experiments that the pigment composition of the chlorophyll alb -binding light-harvesting complex of the green alga Chlorella fusca could be altered in a relatively broad range (Meyer and Wilhelm 1993). In this study we used these reconstituted compl...
