Nanomolar Inhibitors of Trypanosoma brucei RNA Triphosphatase

open access: yesmBio, 2016
Eukaryal taxa differ with respect to the structure and mechanism of the RNA triphosphatase (RTPase) component of the mRNA capping apparatus. Protozoa, fungi, and certain DNA viruses have a metal-dependent RTPase that belongs to the triphosphate tunnel ...

RNA 5′-Triphosphatase, Nucleoside Triphosphatase, and Guanylyltransferase Activities of Baculovirus LEF-4 Protein [PDF]

open access: yesJournal of Virology, 1998
ABSTRACT Autographa californica nuclear polyhedrosis virus late and very late mRNAs are transcribed by an RNA polymerase consisting of four virus-encoded polypeptides: LEF-8, LEF-9, LEF-4, and p47. The 464-amino-acid LEF-4 subunit contains the signature motifs of GTP:RNA guanylyltransferases (capping enzymes).
