A human homologue of the checkpoint kinase Cds1 directly inhibits Cdc25 phosphatase
TLDR
The results suggest that, in human cells, the DNA-damage checkpoint involves direct inactivation of Cdc25 catalyzed by Cds1 and/or Chk1, which is homologous to the CDS1/Rad53 family of checkpoint kinases in yeast. Expand
A novel polar surface polysaccharide from Rhizobium leguminosarum binds host plant lectin
TLDR
In isolation and partial characterization of a novel high molecular weight surface polysaccharide from a strain of Rhizobium leguminosarum that nodulates Pisum sativum and Vicia sativa roots, data are consistent with the hypothesis that rhizobia can use (at least) two mechanisms for docking at the root surface, with use of a lectin–glycan mechanism under slightly acidic conditions. Expand
Role of cellulose fibrils and exopolysaccharides of Rhizobium leguminosarum in attachment to and infection of Vicia sativa root hairs.
Infection and subsequent nodulation of legume host plants by the root nodule symbiote Rhizobium leguminosarum usually require attachment of the bacteria to root-hair tips. Bacterial cellulose fibrilsExpand
Identification of a Human Homologue of theSchizosaccharomyces pombe rad17 + Checkpoint Gene*
TLDR
To begin to understand the protein-protein interactions of the human checkpoint machinery, the yeast two-hybrid system is used to examine potential interactions between Hrad1, Hrad9, and Hrad17 and it is demonstrated that Hrad 17 is located on chromosome 4q13.3–21.2. Expand
Involvement of exo5 in Production of Surface Polysaccharides in Rhizobium leguminosarum and Its Role in Nodulation of Vicia sativa subsp. nigra
TLDR
Analysis of two exopolysaccharide-deficient mutants of Rhizobium leguminosarum revealed independent Tn5 transposon integrations in a single gene, designated exo5, which encodes a UDP-glucose dehydrogenase responsible for the oxidation of UDP-Glucose to UDP- glucuronic acid. Expand
A Human Homologue of the Schizosaccharomyces pombe rad1 + Checkpoint Gene Encodes an Exonuclease*
TLDR
A human homologue of the S. pombe rad1 + gene, designated Hrad1, is identified as well as a mouse homologue: Mrad1, both of which share homology with the Saccharomyces cerevisiaeRAD17 and Ustilago maydis REC1 proteins. Expand
Structures of the lipopolysaccharides from Rhizobium leguminosarum RBL5523 and its UDP-glucose dehydrogenase mutant (exo5).
TLDR
The structures of the RBL5523 parent and RBL5808 mutant LPSs were determined and compared and the mutant was still able to synthesize an LPS containing a normal O-chain polysaccharide (OPS), but at reduced levels. Expand
Rheological properties of patatin gels compared with β-lactoglobulin, ovalbumin, and glycinin.
TLDR
Patatin was found to form gels with comparable small-deformational rheological properties as typical food proteins and is a promising protein to be used in food applications as a gelling agent. Expand
Comprehensive overview of the quality of plant‐ And animal‐sourced proteins based on the digestible indispensable amino acid score
TLDR
Potato, soy, and pea proteins can complement a broad range of plant proteins, leading to higher DIAAS when supplied in the form of protein mixtures and at specific ratios, which highlights the potential to achieve an optimal nutritional efficiency with plant proteins alone. Expand
Exopolysaccharide structure is not a determinant of host-plant specificity in nodulation of Vicia sativa roots.
TLDR
Transconjugation data show that different EPS structures can allow infection-thread formation and subsequent nodulation of V. sativa roots as transconjugants, suggesting that EPS contributes to host-plant specificity of nodulation. Expand
