High impact information on yihX


Chemical compound and disease context of yihX


Biological context of yihX

  • CheZ is the phosphatase of CheY, the response regulator in bacterial chemotaxis [6].
  • Transcriptional and translational cat and phoA fusions to invA (the proximal gene in the invABC operon) were constructed, and their expression was studied by measuring the levels of alkaline phosphatase or chloramphenicol acetyltransferase activity in mutants grown under different conditions [14].
  • In contrast, the PhoP constitutively inactive phenotype observed for the PhoQ-T48L mutant resulted from both decreased autokinase activity and increased phosphatase activity [15].
  • It is concluded that the Salmonella SigD protein deprived of its phosphatase activity is able to disrupt yeast morphogenesis by interfering with Cdc42 function, opening the possibility that the SigD N-terminal region might directly modulate small GTPases from the host during infection [16].
  • Statistical analysis revealed significant differences between the horses which survived and those which died in their packed cell volumes, white blood cell counts, neutrophil counts, serum albumin concentrations and alkaline phosphatase activities [17].

Anatomical context of yihX

  • In reporter gene assays nidulal (1) preferentially activated the transcription factor complex AP-1-mediated expression of secreted alkaline phosphatase in COS-7 cells [18].
  • The identity of the epithelial cells (in the villus tip-to-crypt cell gradient) was monitored by measuring their intracellular alkaline phosphatase activity, while scanning electron microscopy was used to visualize the effects of infection and cell elution techniques [19].
  • The activities of brush border sucrase (72% P < 0.001) and lactase (47% P < 0.01) and alkaline phosphatase (43% P < 0.01) were also significantly reduced in infected animals as compared to the controls [20].

Associations of yihX with chemical compounds


Other interactions of yihX

  • A survey of Salmonella typhimurium enzymes possessing phosphatase or phosphodiesterase activity was made using several different growth conditions [25].
  • Acid phosphatase is regulated via carbon-starvation; although the C. freundii strains overexpressed phosphatase activity in carbon-limiting continuous culture, this was approximately 20-fold less than the activity of strain N14 grown similarly [2].
  • Metal uptake is mediated by the activity of a periplasmic acid-type phosphatase that liberates inorganic phosphate to provide the precipitant ligand for heavy metals presented to the cells [13].

Analytical, diagnostic and therapeutic context of yihX

  • First, after immunoprecipitation of MHC class I from NXS2 cells, peptides were eluted and examined in tandem-MS analysis which lead to the identification of three novel natural MHC class I peptide ligands, TEALPVKLI from ribonucleotide reductase M2, NEYIMSLI from Ser/Thr protein phosphatase 2A and FEMVSTLI with unknown origin [26].
