Potyvirus virion structure shows conserved protein fold and RNA binding site in ssRNA viruses
Potyviruses constitute the second largest genus of plant viruses and cause important economic losses in a large variety of crops; however, the atomic structure of their particles remains unknown. Infective potyvirus virions are long flexuous filaments where coat protein (CP) subunits assemble in helical mode bound to a monopartite positive-sense single-stranded RNA [(+)ssRNA] genome. We present...
متن کاملCrystal Structure of Bacillus subtilis -Amylase in Complex with Acarbose
The crystal structure of Bacillus subtilis -amylase, in complex with the pseudotetrasaccharide inhibitor acarbose, revealed an hexasaccharide in the active site as a result of transglycosylation. After comparison with the known structure of the catalytic-site mutant complexed with the native substrate maltopentaose, it is suggested that the present structure represents a mimic intermediate in t...
متن کاملCrystal structure of DMGO provides a prototype for a new tetrahydrofolate-binding fold.
The crystal structure of DMGO (dimethylglycine oxidase) from Arthrobacter globiformis in complex with folate compounds has revealed a novel THF (tetrahydrofolate)-binding fold [Leys, Basran and Scrutton (2003) EMBO J. 22, 4038-4048]. This fold is widespread among folate-binding proteins. The crystal structures of aminomethyltransferase (T-protein), YgfZ and TrmE all reveal similar THF-binding f...
متن کاملCrystal structure of chorismate synthase: a novel FMN-binding protein fold and functional insights.
Chorismate synthase catalyzes the conversion of 5-enolpyruvylshikimate 3-phosphate to chorismate in the shikimate pathway, which represents an attractive target for discovering antimicrobial agents and herbicides. Chorismate serves as a common precursor for the synthesis of aromatic amino acids and many aromatic compounds in microorganisms and plants. Chorismate synthase requires reduced FMN as...
متن کاملCrystal structure of a new RNA-binding domain from the antiterminator protein SacY of Bacillus subtilis.
SacY belongs to a family of, at present, seven bacterial transcriptional antiterminators. The RNA-binding and antitermination capacity of SacY resides in the 55 amino acids at the N-terminal [SacY(1-55)]. The crystal structure at 2 A resolution shows that SacY(1-55) forms a dimer in the crystal, in accordance with the NMR solution structure. The structure of the monomer is a four-stranded beta-...
