J. Ullrich Physikalisches Institut der Universität, Pfaffenwaldring 57, D-7000 Stuttgart Z. Naturforsch. 40c, 685 — 692 (1985); received May 24, 1985 Rhodopseudomonas sphaeroides, Bacteriochlorophyll a, Bacteriopheophytin a, Bacteriopheophorbide a, Pigment aggregation A series of pigments of the bacteriopheophytin a spectral type have been isolated from ageing cultures of Rhodopseudomonas sphae...
متن کاملPrimary photochemistry of iron-depleted and zinc-reconstituted reaction centers from Rhodopseudomonas sphaeroides.
The primary photochemistry of Fe-depleted and Zn-reconstituted reaction centers from Rhodopseudomonas sphaeroides R-26.1 was studied by transient absorption spectroscopy and compared with native, Fe(2+)-containing reaction centers. Excitation of metal-free reaction centers with 30-ps flashes produced the initial charge-separated state P(+)I(-) (P(+)BPh(-), where P is the primary donor and BPh i...
متن کاملIn vivo metabolic intermediates of phospholipid biosynthesis in Rhodopseudomonas sphaeroides.
The in vivo metabolic pathways of phospholipid biosynthesis in Rhodopseudomonas sphaeroides have been investigated. Rapid pulse-chase-labeling studies indicated that phosphatidylethanolamine and phosphatidylglycerol were synthesized as in other eubacteria. The labeling pattern observed for N-acylphosphatidylserine (NAPS) was inconsistent with the synthesis of this phospholipid occurring by dire...
متن کاملStructure and physical map of Rhodopseudomonas sphaeroides bacteriophage RS1 DNA.
We analyzed, by restriction endonuclease mapping and electron microscopy, the genome of the lytic Rhodopseudomonas sphaeroides-specific bacteriophage RS1 and characterized it as a linear molecule of approximately 60 to 65 kilobases. When the DNA from purified phage particles was examined by several independent methods, considerable size heterogeneity was apparent in the RS1 DNA. This size heter...
متن کاملGenetic transformation of Rhodopseudomonas sphaeroides by plasmid DNA.
A broad-host-range cloning vector, pUI81, was constructed in vitro from plasmids RSF1010 and pSL25 (a pBR322 derivative) and used to assay for transformation in Rhodopseudomonas sphaeroides. Washing cells with 500 mM Tris was an effective means of inducing competence for DNA uptake. Transformation frequencies as high as 10(-5) (transformants per viable cell) have been achieved by incubating Tri...
