polyribonucleotide nucleotidyltransferase (medicine)


polyribonucleotide nucleotidyltransferase
<enzyme> An enzyme of the transferase class that catalyses the reaction RNA(n+1) and orthophosphate to yield RNA(n) and a nucleoside diphosphate, or the reverse reaction. ADP, idp, GDP, udp, and cdp can act as donors in the latter case.

Chemical name: Polyribonucleotide:orthophosphate nucleotidyltransferase

Registry number: EC 2.7.7.8


calcific nodular aortic stenosis (medicine)


calcific nodular aortic stenosis


Most common type of aortic stenosis, occurring usually in elderly men, in which the cusps contain calcified fibrous nodules on both surfaces; the causes include rheumatic fever, atherosclerosis, age-related degeneration, and congenitally bicuspid aortic valve.
