RNA triphosphatase-mediated mRNA capping is essential for maintaining transcript homeostasis and the survival of Toxoplasma gondii [PDF]
Nature CommunicationsRNA modifications are crucial for gene expression in eukaryotes; however, the regulatory role of 5’ 7-methylguanosine (m7G) cap, the first modification of mRNA, remains unknown in the protozoan parasite Toxoplasma gondii.

Hydrogen peroxide yields mechanistic insights into human mRNA capping enzyme function. [PDF]
PLoS ONE, 2017 Capping of nascent RNA polymerase II (Pol II) transcripts is required for gene expression and the first two steps are catalyzed by separate 5' triphosphatase and guanylyltransferase activities of the human capping enzyme (HCE).

Properties of chicken liver membrane-associated thiamine triphosphatase [PDF]
The Ukrainian Biochemical Journal, 2015 The enzymes involved in thiamine triphosphate (ThTP) metabolism in birds are not characterized so far. The aim of the present work was to study some properties of ThTPase in chicken liver.

Halobacterial adenosine triphosphatases and the adenosine triphosphatase fromHalobacterium saccharovorum [PDF]
FEMS Microbiology Letters, 1986 Membranes prepared from various members of the genus Halobacterium contained a Triton X-100 activated adenosine triphosphatase. The enzyme from Halobacterium saccharovorum was unstable in solutions of low ionic strength (< 3 M NaCl) and maximally active in the presence of 3.5 M NaCl. A variety of nucleotide triphosphates was hydrolyzed.

RNA triphosphatase is essential in
BMC Microbiology, 2001 Background The first two steps in the capping of cellular mRNAs are catalyzed by the enzymes RNA triphosphatase and RNA guanylyltransferase. Although structural and mechanistic differences between fungal and mammalian RNA triphosphatases recommend this ...
