Unusual tRNA nucleotidyltransferases: Adaptation of the Romanomermis culicivorax CCA-adding enzyme towards armless tRNAs and characterization of the phosphodiesterase domain of the Escherichia coli CCA-adding enzyme

, 2022
tRNAs spielen eine zentrale Rolle in jedem bekannten Organismus. Sie agieren als Adaptoren, um den Code der Nukleinsäuren in eine funktionale Aminosäuresequenz zu übersetzen.

Identification d'une Terminal Uridylyl Transférase impliquée dans la protection de l'extrémité 3' des ARNm déadénylés chez Arabidopsis thaliana

, 2012
The work presented in this manuscript defines a new role of mRNA uridylation, using Arabidopsis as a model organism. RNA uridylation is catalyzed by RNA nucleotidyltransferases belonging to the non canonical poly(A) polymerase (ncPAP) family.

Functional and mechanistic aspects of endogenous RNAi in C. elegans

, 2009
RNAi is widely used as a genetic tool in a range of model organisms, however still relatively little is known about the endogenous functions of RNAi. In this thesis we have studied several aspects of the endogenous role of RNAi in order to enhance our ...

Poly(A)-specific ribonuclease에 의한 microRNA 3′ 말단 형성에 대한 연구 [PDF]

, 2019
학위논문 (박사)-- 서울대학교 대학원 : 농업생명과학대학 농생명공학부, 2019. 2. 신찬석.The 3′ ends of metazoan microRNAs (miRNAs) are initially defined by the RNase III enzymes during maturation, but subsequently experience extensive modifications by several enzymatic activities.

DataSheet_1_Manipulation of mitochondrial poly(A) polymerase family proteins in Trypanosoma brucei impacts mRNA termini processing.pdf

RNA-specific nucleotidyltransferases (rNTrs) add nontemplated nucleotides to the 3′ end of RNA. Two noncanonical rNTRs that are thought to be poly(A) polymerases (PAPs) have been identified in the mitochondria of trypanosomes – KPAP1 and KPAP2.

Antibiotic Resistance and the Cellular Currency S-adenosyl-methionine : Modification of aminoglycosides and nucleic acids

, 2020
Streptomycin and spectinomycin are antibiotics that bind to ribosomes and inhibit protein synthesis. Common resistance mechanisms involve enzymatic modification of the two drugs by aminoglycoside nucleotidyltransferases (ANTs).
