Dynein motors are biologically important bio-nanomachines, and many atomic resolution structures of cytoplasmic dynein components from different organisms have been analyzed by X-ray crystallography, cryo-EM, and NMR spectroscopy. This review provides a historical perspective of structural studies of cytoplasmic and axonemal dynein including accessory proteins. We describe representative structural studies of every component of dynein and summarize them as a structural atlas that classifies thedoi:10.1007/s12551-018-0402-y pmid:29478092 pmcid:PMC5899744 fatcat:5526c7m7sjf7nkgu3piu7dhr2a

Structures of the cytochrome b 6 f complex obtained from the thermophilic cyanobacterium Mastigocladus laminosus and the green alga Chlamydomonas reinhardtii, whose appearance in evolution is separated by 10 9 years, are almost identical. Two monomers with a molecular weight of 110 000, containing eight subunits and seven natural prosthetic groups, are separated by a large lipid-containing "quinone exchange cavity". A unique heme, heme x, that is five-coordinated and high-spin, with no strongdoi:10.1021/bi049444o pmid:15147175 fatcat:fkjwpz4z4rbkpjbjtues6glepq

This position is filled by the n-side bound quinone, Q n , in the cytochrome bc 1 complex of the mitochondrial respiratory chain. The structure and position of heme x suggest that it could function in ferredoxin-dependent cyclic electron transport as well as being an intermediate in a quinone cycle mechanism for electron and proton transfer. The significant differences between the cyanobacterial and algal structures are as follows. (i) On the n-side, a plastoquinone molecule is present in the quinone exchange cavity in the cyanobacterial complex, and a sulfolipid is bound in the algal complex at a position corresponding to a synthetic DOPC lipid molecule in the cyanobacterial complex. (ii) On the p-side, in both complexes a quinone analogue inhibitor, TDS, passes through a portal that separates the large cavity from a niche containing the Fe 2 S 2 cluster. However, in the cyanobacterial complex, TDS is in an orientation that is the opposite of its position in the algal structure and bc 1 complexes, so its headgroup in the M. laminosus structure is 20 Å from the Fe 2 S 2 cluster. † The studies reported in this review were supported by NIH Grant GMS-38323 (W.A.C.) and a fellowship from The Japanese Ministry of Education (G.K.).

Cytoplasmic dynein is responsible for intra-cellular transport in eukaryotic cells. Using Fluctuating Finite Element Analysis (FFEA), a novel algorithm that represents proteins as continuum viscoelastic solids subject to thermal noise, we are building computational tools to study the mechanics of these molecular machines.

Plants provide nourishment for animals and other heterotrophs as the sole primary producer in the food chain. Glutamine synthetase (GS), one of the essential enzymes for plant autotrophy catalyzes the incorporation of ammonia into glutamate to generate glutamine with concomitant hydrolysis of ATP, and plays a crucial role in the assimilation and re-assimilation of ammonia derived from a wide variety of metabolic processes during plant growth and development.

Here we report the first crystal structures of maize (Zea mays L.) GS. The structure reveals a unique decameric structure that differs significantly from the bacterial GS structure. Higher plants have several isoenzymes of GS differing in heat stability and catalytic properties for efficient responses to variation in the environment and nutrition. A key residue responsible for the heat stability was found to be Ile-161 in GS1a. The three structures in complex with substrate analogues, including phosphinothricin, a widely used herbicide, lead us to propose a mechanism for the transfer of phosphate from ATP to glutamate and to interpret the inhibitory action of phosphinothricin as a guide for the development of new potential herbicides. * This work was supported by the Ministry of Education, Culture, Sports, Science, and Technology (MEXT), Japan.

After the single structures of ferredoxin and ferredoxin-NADP+ reductase have been reported, no complex structure of them was reported. Here we report the crystallization of the electron transfer complex between ferredoxin and ferredoxin-NADP+ reductase from maize leaf and the structure analysis of this complex at 2.59 A resolution. The structures of ferredoxin and ferredoxin-NADP+ reductase in this complex state differ from the structures of single states.

2,3-Butanediol dehydrogenase (BDH) catalyzes the NAD-dependent redox reaction between acetoin and 2,3-butanediol. There are three types of homologous BDH, each stereospecific for both substrate and product. To establish how these homologous enzymes possess differential stereospecificities, we determined the crystal structure of L-BDH with a bound inhibitor at 2.0 Å. Comparison with the inhibitor binding mode of meso-BDH highlights the role of a hydrogen-bond from a conserved Trp residue 192 .doi:10.1016/j.febslet.2009.11.068 pmid:19941855 fatcat:jdk4zayhnrhnxjz65okfcjk5f4

This result confirms the importance of conserved residues in modifying the stereospecificity of homologous enzymes.
