Ribonuclease P Catalysis: Metal Ion Interaction and Conformational Dynamics [PDF]

open access: yes, 2015
RNase P is responsible for catalyzing the 5’-end maturation of precursor tRNAs (pre-tRNAs). The catalytic RNA subunit of bacterial RNase P is essential for activity.

Kinetic studies on the fidelity of DNA replication involving DNA templates containing O6-methylguanine [PDF]

open access: yes, 1993
Production by N-nitroso compounds of O6-alkylguanine (O6-alkylG) in DNA directs the misincorporation of thymine during DNA replication, leading to G:C to A:T transition mutations, despite the fact that DNA containing O6>alkylG:T base-pairs is less ...

Some studies on the low molecular weight RNA components of mammalian cells [PDF]

open access: yes, 1971
Until recently, RNA was considered to belong to one of three categories; transfer RNA(tRNA), ribosomal RNA or messenger RNA. In addition however, the development of more sophisticated analytical techniques such as polyacrylamide gel electrophoresis ...

ATP-binding cassette subfamily C (ABCC) transporter 1 (ABCC1) and 4 (ABCC4) independent of their drug efflux ability affects breast cancer biology [PDF]

open access: yes
Breast cancer treatment has been a challenge to date, due in part to cancer cells acquiring drug resistance. One of the mechanisms by which resistance can occur is the overexpression of drug efflux pumps such as ATP-binding cassette, subfamily C (ABCC ...
