Reconstructing the set of prokaryote communities, it is possible to imagine a speculative scenario for an interacting ecosystem (Fig. 7). 

Often the coding process for degradation of a xenobiotic is contained in both the extrachromosomal DNA, the plasmid, and the chromosome. Often the initial steps that lead to the eventual incorporation of the material into the TCA cycle are coded by the plasmid. Of course, two pathways may exist, a chromosomal and a plasmid pathway. Given the proper DNA probes, pieces of DNA with complimentary sequences to the degradation genes, it should be possible to follow the frequency and thereby the population genetics of degradative plasmids in prokaryotic communities.

Electron Transport Between Photosystem I and Photosystem II Inhibitors. The interaction between PSI and PSII reaction centers (Fig. 1) depends on the thermodynamically favored transfer of electrons from low redox potential carriers to carriers of higher redox potential. This process serves to communicate reducing equivalents between the two photosystem complexes. Photosynthetic and respiratory membranes of both eukaryotes and prokaryotes contain stmctures that serve to oxidize low potential quinols while reducing high potential metaHoproteins (40). In plant thylakoid membranes, this complex is usually referred to as the cytochrome b /f complex, or plastoquinolplastocyanin oxidoreductase, which oxidizes plastoquinol reduced in PSII and reduces plastocyanin oxidized in PSI (25,41). Some diphenyl ethers, eg, 2,4-dinitrophenyl 2 -iodo-3 -methyl-4 -nitro-6 -isopropylphenyl ether [69311-70-2] (DNP-INT), and the quinone analogues,...

Table I shows that many domain families are widespread among fungi, plants, and metazoa and yet are absent from prokaryotes. It is assumed that these domains arose in early eukaryotes before the emergence of these three major eukaryotic lineages. Consideration of the known functions of these domains, and the proteins in which they occur, strongly suggests that emergence of several cellular functions that are unique to eukaryotes occurred in early eukaryotic history. These functions are likely to have coevolved with the abilities of the protoeukaryotic cell to reproduce sexually and to partake in cell—cell communication. Here we review several eukaryotic-specific domain families as illustrations of the coevolution of domain families with cellular functions.

The Shaker potassium channel did not yield crystals for the first potassium ion channel X-ray crystallographic structure. Rather, it was the prokaryote bacterium Streptomyces lividans, abbreviated as the KcsA K+ channel, that first produced crystals suitable for crystallography. This structure, published in 1998 by MacKinnon s group in Science magazine, was received with great praise from the scientific community. It was known at that time that the amino acid sequence of KcsA was similar to that of other K channels, including vertebrate and invertebrate voltage-dependent K (Kv) channels (such as the...
