The mitochondrial carrier Rim2 co-imports pyrimidine nucleotides and iron.
Mitochondrial iron uptake is of key importance both for organelle function and cellular iron homoeostasis. The mitochondrial carrier family members Mrs3 and Mrs4 (homologues of vertebrate mitoferrin) function in organellar iron supply, yet other low efficiency transporters may exist. In Saccharomyces cerevisiae, overexpression of RIM2 (MRS12) encoding a mitochondrial pyrimidine nucleotide trans...
متن کاملSeqVis: Visualization of compositional heterogeneity in large alignments of nucleotides
UNLABELLED Most phylogenetic methods assume that the sequences evolved under homogeneous, stationary and reversible conditions. Compositional heterogeneity in data intended for studies of phylogeny suggests that the data did not evolve under these conditions. SeqVis, a Java application for analysis of nucleotide content, reads sequence alignments in several formats and plots the nucleotide cont...
متن کاملConcentrations of purine nucleotides and purine and pyrimidine bases in cerebrospinal fluid of neurologically healthy children.
The concentrations of the nucleotides AMP and IMP, the nucleosides adenosine, guanosine and inosine, the purine bases adenine, guanine, hypoxanthine and xanthine, urate, and the pyrimidine bases cytosine, thymine and uracil were determined by high performance liquid chromatography in the cerebrospinal fluid of 63 children aged between 1 month and 13 years who showed no sign of neurological dise...
متن کاملCatabolism of pyrimidine nucleotides in the deep-sea tube worm Riftia pachyptila.
The present study describes the distribution and properties of enzymes of the catabolic pathway of pyrimidine nucleotides in Riftia pachyptila, a tubeworm living around deep-sea hydrothermal vents and known to be involved in a highly specialized symbiotic association with a bacterium. The catabolic enzymes, 5'-nucleotidase, uridine phosphorylase, and uracil reductase, are present in all tissues...
متن کاملBiosynthesis of pyrimidine nucleotides in mouse salivary glands stimulated with isoproterenol.
Cellular proliferation was stimulated with isoproterenol in submaxillary glands of mice. The activities ‘of both carbamyl-P synthetase and aspartate transcarbamylase were rapidly increased in response to isoproterenol, reaching a peak between 4 and 6 hours. The increase in activity of carbamyl-P synthetase was 2-fold, the increase in aspartate transcarbamylase was 1.5-fold. Incorporation of WO2...
