EMBO J . 1999 Dec; 18(23):6705-17. PMID: 10581244
Approaches have been developed for the kinetic dissection of eukaryotic translation initiation in vitro using rabbit reticulocyte ribosomes and a crude preparation of initiation factors. These new approaches have allowed...

Lorsch J, Herschlag D
Biochemistry . 1998 Mar; 37(8):2194-206. PMID: 9485365
Limited proteolysis experiments have been carried out with the DEAD box protein eIF4A. The results suggest that there is a substantial conformational change in eIF4A upon binding single-stranded RNA. Binding...

Lorsch J, Herschlag D
Biochemistry . 1998 Mar; 37(8):2180-93. PMID: 9485364
eIF4A is the archetypal member of the DEAD box family of proteins and has been proposed to use the energy from ATP hydrolysis to unwind structures in the 5'-untranslated regions...

Lorsch J, Szostak J
Acc Chem Res . 1996 Feb; 29(2):103-10. PMID: 11539421
In Tom Stoppard's famous play [Rosencrantz and Guildenstern are Dead], the ill-fated heroes toss a coin 101 times. The first 100 times they do so the coin lands heads up....

Lorsch J, Szostak J
Biochemistry . 1995 Nov; 34(46):15315-27. PMID: 7578148
We have previously isolated a series of ribozymes with polynucleotide kinase activity [Lorsch, J.R., & Szostak, J.W. (1994) Nature 371, 31-36]. In order to learn how such newly evolved RNAs...

Nucleic Acids Res . 1995 Aug; 23(15):2811-4. PMID: 7544885
Avian myeloblastosis virus and Maloney murine leukemia virus RNase H-reverse transcriptases pause when they encounter a 2'-5' linkage or a 2'-thiophosphate in their template RNAs, but eventually read through these...

Lorsch J, Szostak J
Nature . 1994 Sep; 371(6492):31-6. PMID: 7521014
We have isolated a large number of polynucleotide kinase ribozymes from a pool of RNA molecules consisting of an ATP-binding domain flanked by regions of random sequence. Different classes of...

Biochemistry . 1994 Feb; 33(4):973-82. PMID: 7508262
RNA receptors (aptamers) capable of specifically binding cyanocobalamin (vitamin B12) have been isolated by in vitro selection from a pool of 5 x 10(14) RNAs of random sequence. After eight...
