Abstract
The green alga Chlamydomonas reinhardtii contains six plastidic [2Fe2S]-cluster ferredoxins (FDXs), with FDX1 as the predominant isoform under photoautotrophic growth. FDX2 is highly similar to FDX1 and has been shown to interact with specific enzymes (such as nitrite reductase), as well as to share interactors with FDX1, such as the hydrogenases (HYDA), ferredoxin:NAD(P) reductase I (FNR1), and pyruvate:ferredoxin oxidoreductase (PFR1), albeit performing at low catalytic rates. Here we report the FDX2 crystal structure solved at 1.18 Å resolution. Based on differences between the Chlorella fusca FDX1 and C. reinhardtii FDX2 structures, we generated and purified point-mutated versions of the FDX2 protein and assayed them in vitro for their ability to catalyze hydrogen and NADPH photo-production. The data show that structural differences at two amino acid positions contribute to functional differences between FDX1 and FDX2, suggesting that FDX2 might have evolved from FDX1 toward a different physiological role in the cell. Moreover, we demonstrate that the mutations affect both the midpoint potentials of the FDX and kinetics of the FNR reaction, possibly due to altered binding between FDX and FNR. An effect on H2 photo-production rates was also observed, although the kinetics of the reaction were not further characterized.

Abstract
Ferredoxins (FDXs) can distribute electrons originating from photosynthetic water oxidation, fermentation, and other reductant-generating pathways to specific redox enzymes in different organisms. The six FDXs identified in Chlamydomonas reinhardtii are not fully characterized in terms of their biological function. In this report, we present data from the following: (a) yeast two-hybrid screens, identifying interaction partners for each Chlamydomonas FDX; (b) pairwise yeast two-hybrid assays measuring FDX interactions with proteins from selected biochemical pathways; (c) affinity pulldown assays that, in some cases, confirm and even expand the interaction network for FDX1 and FDX2; and (d) in vitro NADP(+) reduction and H2 photo-production assays mediated by each FDX that verify their role in these two pathways. Our results demonstrate new potential roles for FDX1 in redox metabolism and carbohydrate and fatty acid biosynthesis, for FDX2 in anaerobic metabolism, and possibly in state transition. Our data also suggest that FDX3 is involved in nitrogen assimilation, FDX4 in glycolysis and response to reactive oxygen species, and FDX5 in hydrogenase maturation. Finally, we provide experimental evidence that FDX1 serves as the primary electron donor to two important biological pathways, NADPH and H2 photo-production, whereas FDX2 is capable of driving these reactions at less than half the rate observed for FDX1.

Abstract
We have determined the crystal structure, at 1.2-A resolution, of Equisetum arvense ferredoxin isoform II (FdII), which lacks residues equivalent to Arg(39) and Glu(28) highly conserved among other ferredoxins (Fds). In other Fds these residues form an intramolecular salt bridge crucial for stabilization of the [2Fe-2S] cluster, which is disrupted upon complex formation with Fd-NADP(+) oxidoreductase (FNR) to form two intermolecular salt bridges. The overall structure of FdII resembles the known backbone structures of E. arvense isoform I (FdI) and other plant-type Fds. Dramatically, in the FdII structure a unique, alternative salt bridge is formed between Arg(22) and Glu(58). This results in a different relative orientation of the alpha-helix formed by Leu(23)-Glu(29) and eliminates the possibility of forming three of the five intermolecular salt bridges identified on formation of a complex between maize FdI and maize FNR. Mutation of FdII, informed by structural differences with FdI, showed that the alternative salt bridge and the absence of an otherwise conserved Tyr residue are important for the alternative stabilization of the FdII [2Fe-2S] cluster. We also investigated FdI and FdII electron transfer to FNR on chloroplast thylakoid membranes. The K(m) and V(max) values of FdII are similar to those of FdI, contrary to previous measurements of the reverse reaction, from FNR to Fd. The affinity between reduced FdI and oxidized FNR is much greater than that between oxidized FdI and reduced FNR, whereas this is not the case with FdII. The pH dependence of electron transfer by FdI, FdII, and an FdII mutant with FdI features was measured and further indicated that the binding mode to FNR differs between FdI and FdII. Based on this evidence, we hypothesize that binding modes with other Fd-dependent reductases may also vary between FdI and FdII. The structural differences between FdI and FdII therefore result in functional differences that may influence partitioning of electrons into different redox metabolic pathways.

Abstract
We report the observation of paramagnetically shifted (hyperfine) proton resonances from vertebrate mitochondrial [2Fe-2S] ferredoxins. The hyperfine signals of human, bovine, and chick [2Fe-2S] ferredoxins are described and compared with those of Anabaena 7120 vegetative ferredoxin, a plant-type [2Fe-2S] ferredoxin studied previously [Skjeldal, L., Westler, W. M., & Markley, J. L. (1990) Arch. Biochem. Biophys. 278, 482-485]. The hyperfine resonances of the three vertebrate ferredoxins were very similar to one another both in the oxidized state and in the reduced state, and slow (on the NMR scale) electron self-exchange was observed in partially reduced samples. For the oxidized vertebrate ferredoxins, hyperfine signals were observed downfield of the diamagnetic envelope from +13 to +50 ppm, and the general pattern of peaks and their anti-Curie temperature dependence are similar to those observed for the oxidized plant-type ferredoxins. For the reduced vertebrate ferredoxins, hyperfine signals were observed both upfield (-2 to -18 ppm) and downfield (+15 to +45 ppm), and all were found to exhibit Curie-type temperature dependence. This pattern and temperature dependence are distinctly different from those found with reduced plant-type ferredoxins which have signal centered around +120 ppm with Curie-type temperature dependence, assigned to cysteines which interact with Fe(III), and signals centered around +20 ppm with anti-Curie temperature dependence, assigned to cysteines which interact with Fe(II) [Dugad, L.

Abstract
A procedure for the isolation of maleic acid hydratase (D-malate hydro-lyase, EC 4.2.1.31) of about 95% purity from rabbit kidneys is described. The enzyme consists of a single polypeptide chain of 582 amino-acid residues with an approximate molecular mass of 68 kDa. The enzyme is very unstable and has an absolute requirement for chloride ions. Addition of sodium sulphide during the purification process was essential to maintain the enzyme in an activatable state. The pure preparation has low activity but responds to activation with Fe2+ ions, Na2S and a thiol. The sequence of adding the activating reagents is critical to achieve optimal activity. Ni2+ and to a lesser extent Co2+ can replace iron in the activation process. The enzyme incorporates 4-5 mol iron/mol and 4.5-6 mol sulphide/mol during activation. In this process an [Fe-S] cluster appears to be built up, as indicated by optical and electron paramagnetic resonance (EPR) spectroscopy. In activated samples exposed to air the [Fe-S] cluster is EPR-detectable through an axial signal with g = 2.01 and g = 2.029 whose temperature and power saturation characteristics were similar to those of other [3Fe-xS] clusters. The activated enzyme, however, is readily inactivated even upon minor manipulation with destruction of the iron-sulfur core.

Abstract
The complete amino-acid sequences of two isocytochromes c (larval- and adult-type cytochromes c) purified from the housefly Musca domestica L. were determined. Their sequences differed at six positions from each other. More than 90% of the total cytochrome c was larval-type during larval stages. The amount of adult-type cytochrome c increased rapidly from 1 day before adult emergence, making the total cytochrome c content increase to approximately 2.5-times as much cytochrome c content as in larvae. Although the major cytochrome c species in flight muscles was adult-type, imaginal disks contained mainly larval-type cytochrome c.

Abstract
Spinach ferredoxin contains a single ferredoxin which can be chemically modified with diethylpyrocarbonate. By varying the concentration of diethylpyrocarbonate modified ferredoxins could be prepared which had only one or both of the imidazole nitrogens of the histidine modified. A small amount of tyrosine was also modified. Ferredoxin with only one of the imidazole nitrogens modified was fully active in NADP photoreduction by chloroplast membranes. This activity was lost as the second imidazole nitrogen was modified. The results suggest an essential role for the single histidine of ferredoxin.

Abstract
Highly purified ferredoxin-NADP+ reductase from spinach leaves showed at least eight different protein bands in the electrofocused gel. All of them were catalytically active and were adsorbed on a ferredoxin-Sepharose 4B affinity column. The N-terminal amino acid sequence of the main component species was analyzed by the automatic Edman degradation method. It was found that when the reductase was stored at 4 degrees C, new protein bands appeared in isoelectric focusing and sodium dodecyl sulfate polyacrylamide gel electrophoreses, but the appearance of the bands was suppressed by the addition of a protease inhibitor, diisopropyl fluorophosphate. This indicates that the molecular heterogeneity of the reductase may result from the digestion with a protease present in spinach leaves.

Abstract
The amino acid sequence of cytochrome c-550 from the chemoautotroph, Nitrobacter agilis, was completed by using solid-phase sequencing and conventional procedures. The cytochrome was composed of 109 amino acid residues and its molecular weight was calculated to be 12375 including haem c. The cytochrome was homologous to eukaryotic cytochromes c and some photosynthetic bacterial cytochromes c2. In particular, its primary structure was very similar to that of Rhodopseudomonas viridis cytochrome c2. Some of its properties were compared with those of other cytochromes c on the basis of the primary structure.

Abstract
1. Antibodies were produced in rabbits to the 4Fe-4S ferrodoxins from Bacillus stearothermophilus, the 2 [4Fe-4S] ferredoxin from Clostridium pasteurianum, and the 2Fe-2S ferredoxins from the blue-green algia Spirulina maxima, the green alga Scenedesmus obliquus, and the higher plant Beta vulgaris. The antibodies were tested for immunoprecipitation activity with seven bacterial, twelve blue-green algal, six eukaryotic algal and six higher plant ferredoxins. 2. Antibodies to the bacterial ferredoxins reacted to a significant extent only with their homologous proteins. On the other hand, antibodies to the plant and algal ferredoxins showed cross-reaction with other ferredoxins. There was a correlation between the degrees of immunoprecipitation and the similarity in amino acid sequences. These results suggest that the method can be used as a marker in taxonomic studies. 3. The interaction of the antibodies with the five native ferredoxins was compared with the reactions with their apoproteins. In each case the degree of interaction was different. This behaviour was interpreted as due to an influence of tertiary structure on the antibody-antigen interaction.

Abstract
Ferredoxins were isolated and purified from leaves of different species of Nicotiana and Petunia and from spinach leaves. Their spectral properties, degree of homogeneity, and molecular weights were determined. The preparations were further analyzed by polyacrylamide gel electrophoresis of tryptic hydrolysates. This allowed us to distinguish between not only ferredoxins of Nicotiana, Petunia, and spinach, but even ferredoxins of various Nicotiana species. We used the differences in tryptic peptide compositions as phenotypic markers to study the mode of inheritance of chloroplast ferredoxin to see whether the coding site is in the chloroplast or in the nucleus. Analysis of the tryptic peptide composition of ferredoxin from different interspecific hybrids of Nicotiana showed that the characteristics of both parental ferredoxins were present. The results indicate that the primary structure of at least the male ferredoxin is coded for in the nucleus. In some of the hybrids the relative contribution of the male parent appeared to be low, suggesting that the female genome (presumably that part located in the plastome) exerted a dominating influence.

Abstract
The proteolytic specificity of thermolysin has been studied by quantitative analysis of an enzymic digest of dog myoglobin. Results confirm main specificities of thermolysin towards Phenylalanine, Isoleucine, Leucine or Tyrosine bonds; the influence of neighbourhood was also determined and the conclusions are in a good agreement with the known structure of the active site of thermolysin.

Abstract
Ferredoxin was purified from 10 species of Nicotiana and spinach leaves. Fingerprints showed all to contain five major tryptic peptides. Some of the spinach peptides were different in RF and mobility from the Nicotiana peptides, but none of the Nicotiana ferredoxins had peptides which could distinguish one species of ferredoxin from another. Electrofocusing S-carbaminomethylcysteinyl ferredoxins showed spinach ferredoxin to have a more acidic and N. glutinosa ferredoxin a slightly more acidic isoelectric point than the other 9 Nicotiana species which were alike. Electro-focusing ferredoxin from the hybrid N. glutinosa female times N. glauca male resolved two bands or isozymes of ferredoxin, one corresponding to N. glutinosa, the other to N. glauca, the code for the latter having come from the DNA in the N. glauca pollen used to form the hybrid plant. N. glutinosa ferredoxin does not contain methionine and is different from N. tabacum and N. glauca ferredoxins which contain methionine. The N. glutinosa female times N. glauca male ferredoxin contained one-half the methionine found in N. glauca ferredoxin, thus confirming that some of the genetic information for ferredoxin in the hybrid was originally contained in the nuclear DNA of N. glauca.

Abstract
Ferredoxin from the alga Bumilleriopsis filiformis Vischer (Xanthophyceae) is characterized by comparing some of its properties with spinach ferredoxin.It is similar to the known plant ferredoxins in the following points: a) Absorption spectrum. b) Molecular weight. c) Amino acid composition (approx. 100 amino acid residues). d) Uptake of 1 electron upon complete reduction and a 50 per cent decrease of the optical density at 420 nm. e) 2 non-heme iron atoms per molecule, which do not exchange with an iron isotope. f) SH-groups of the native protein do not react with DTNB. Bumilleriopsis ferredoxin differs from known plant ferredoxins in the following points: a) Greater stability towards atmospheric oxygen when gently heated. b) Only 1 detectable acid-labile sulfur atom per molecule. c) Dialysis against EDTA: by this procedure a part of the iron but none of the acid-labile sulfur is removed. With spinach ferredoxin a part of both elements is removed simultaneously. d) Greater reactivity with ferredoxin-NADP reductase from Bumilleriopsis than with that from spinach. With spinach ferredoxin no substantial difference between the reaction rates of the two reductases is observed (see Böger, 1969 b). The results may indicate an active center in Bumilleriopsis ferredoxin consisting of 1 atom iron and 1 atom acid-labile sulfur.
