标题 :Convergent synthesis of multiporphyrin light-harvesting rods
发明人：LINDSEY JONATHAN S; LOEWE ROBERT S
权利人:UNIV NORTH CAROLINA STATE
摘要:The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A 1 (A b+1 ) b , wherein b is at least 1, A 1 through A b+1 are covalently coupled rod segments, and each rod segment A 1 through A 1+b comprises a compound of the formula X 1 (X m+1 ) m wherein m is at least 1 and X 1 through X m+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.

标 题 :Method for the microbial production of metabolic products, polynucleotides from coryneform bacteria and use thereof
发明人：BOTT MICHAEL; NIEBISCH AXEL; BATHE BRIGITTE; MARX ACHIM; HERMANN THOMAS
摘要:The invention relates to a method for the microbial production of metabolic products, polynucleotides from coryne-form bacteria and use thereof. According to the invention, by means of said method and polynucleotides it is possible to influence the synthesis of ATP in a controlled manner and also to control the synthesis of metabolic products. The invention relates to genes from Corynebacterium glutamicum coding for cytochrome aa 3 oxidase and the cytochrome bc 1 complex. The monocistronic ctaD gene codes for a 65 kDa protein, the primary structure of which displays all the typical properties of the sub-unit I of cytochrome aa 3 oxidase. The genes which code for the sub-unit III of the cytochrome aa 3 (ctaE) and the three characteristic sub-units of the cytochrome bc 1 complex (qcrABC) are arranged in a group with the sequence ctaE-qcrCAB. An analysis of the derived primary structure shows a sequence with unusual properties: (i) cytochrome C 1 (QcrC, 30 kDa) contains two Cys-X—X-Cys-His groups for the covalent bonding of haeme, which means that said protein is a di-haeme cytochrome of the c type; (ii) the “Rieskeâ€? iron-sulphur protein (QcrA, 45 kDa) presumably contains three trans-membrane helices in the N-terminal region; (iii) cytochromeb (QcrB, 60 kDa) contains a C-terminal extension of 120 amino acids, along with the conserved region with 8 trans-membrane helices, presumably localised in the cytoplasma. The electron transfer from the cytochrome bc 1 complex to the cytochrome aa 3 terminal oxidase does not involve additional ctochrome c.
