Irradiation of DNA with UV-B light causes the formation of mutagenic DNA lesions such as cis−syn and trans−syn cyclobutane pyrimidine dimers. DNA photolyases are flavin-dependent repair enzymes which directly revert the mutagenic cis−syn pyrimi

Methods are described for the synthesis of bis-diazene precursors of catenated tetraradicals. Photodeazetation in a low-temperature matrix of the N-tosylpyrrole member of the series (13) gives mainly the monodeazetated biradical 34, which is characte

5,6-Dihydrothymid-5-yl (4) is generated via Norrish type I cleavage of isopropyl ketone 7. Ketone 7 was site specifically incorporated into chemically synthesized polythymidylates and an oligonucleotide containing all four native deoxyribonucleotides

The kinetics of the reaction of a series of aromatic and aliphatic thiols with cluster 1 were determined. These reactions form cluster 2 and the arene or alkane corresponding to the thiol: Cp‘2Mo2Co2S3(CO)4 (1) + RSH → Cp‘2Mo2Co2S4(CO)2 (2) + R

Photostimulated additions of tert-butylmercury halides to 1,6-dienes and enynes, including (CH2CHCH2)2X with X = CH2, C(COEt)2, O, or NCH2CHCH2, form the primary alkylmercury halides resulting from 5-exo-cyclizations of the adduct radicals, t-BuCH2CH

The application of a recently developed technique of conformational memories (Guarnieri, F.; Wilson, S. R. J. Comput. Chem. 1995, 16, 5, 648) to the study of peptide structure is illustrated with an analysis of the conformational populations of the d

A novel cross-linked pyroelectric polymer with pronounced second-order nonlinear optical properties has been prepared. A multistep synthesis with several selective transformations including a kinetic resolution (transesterification) with the highly e

Human α-1,3-fucosyltransferase V (FucT V), which catalyzes the transfer of l-fucose moiety from guanosine diphosphate β-l-fucose (GDP-Fuc) to an acceptor sugar to form sialyl Lewis x (sLex), was shown to proceed through an ordered, sequential mecha

This manuscript describes the bulk synthesis of shape persistent two-dimensional (2D) polymers using the self-assembly of rigid precursor moelcules into bilayers. A precursor was synthesized with a structure that encodes for the necessary molecular r

One of the factors hindering the development of technologies that rely on the use of proton-conducting polyelectrolyte membranes is the lack of control over the membrane morphology on the nanoscale. Of particular importance is the rearrangement and c
