Words similar to guanylyltransferase
Example sentences for: guanylyltransferase
How can you use “guanylyltransferase” in a sentence? Here are some example sentences to help you improve your vocabulary:
S. pombe RNA triphosphatase Pct1 is a 303-amino acid polypeptide with a homodimeric quaternary structure [ 12 ] . The pct1 +gene contains a single intron within the open reading frame [ 12 ] . S. pombe RNA guanylyltransferase Pce1 is a 402-amino acid monomeric protein [ 20 ] ; there are no introns within the pce1 +gene.
[ 25 ] had previously generated a single allele knockout in C. albicans of the guanylyltransferase component of the capping apparatus (Cgt1) using the URA-blaster technique and noted a variety of pleiotrophic effects on stress response, hygromycin sensitivity, and colony morphology in the CGT1/cgt1Δ heterozygote, but they found that the heterozygote was just as virulent as the wild-type strain in animal models of systemic candidiasis.
The cap is formed by three enzymatic reactions: the 5' triphosphate end of the nascent pre-mRNA is hydrolyzed to a diphosphate by RNA triphosphatase; the diphosphate end is capped with GMP by RNA guanylyltransferase; and the GpppN cap is methylated by RNA (guanine-7-) methyltransferase [ 1 ] .
Here we constructed pct1Δ and pce1Δ plasmids containing 5' and 3' flanking genomic sequences in which the entire triphosphatase or guanylyltransferase coding sequence was deleted and replaced by the kanamycin resistance gene [ 17 ] . The pct1::kanMX and pce1::kanMX constructs were transformed separately into a diploid strain of S. pombe and chromosomal integrants containing one copy of the wild-type gene and one of pct1::kanMX or pce1::kanMX were selected on medium containing G418.
Although the three capping reactions are universal in eukaryotes, there is a surprising diversity in the genetic organization of the capping enzymes as well as a complete divergence in the structure and catalytic mechanism of the RNA triphosphatase component in "lower" versus "higher" eukaryotic species [ 1 ] . Metazoans and plants have a two-component capping system consisting of a bifunctional triphosphatase-guanylyltransferase polypeptide and a separate methyltransferase polypeptide, whereas fungi contain a three-component system consisting of separate triphosphatase, guanylyltransferase, and methyltransferase gene products.
