Lactose repressor protein has been modified with N-ethylmaleimide, two N-maleimide spin labels, and an N-maleimide fluorophore. The reaction with repressor cysteine residues has been characterized. Approximately 2 of the 3 eq of cysteine/repressor monomer are reactive toward these reagents. Repressor cysteines are reactive toward these reagents in the order cysteine 140 greater than or equal to...
Carbon-carbon bond formation is the basis for the biogenesis of nature's essential molecules. Consequently, it lies at the heart of the chemical sciences. Chiral catalysts have been developed for asymmetric C-C bond formation to yield single enantiomers from several organometallic reagents. Remarkably, for extremely reactive organolithium compounds, which are among the most broadly used reagent...

The protein structural entries grew far slower than the sequence entries. This is partly due to the bottleneck in obtaining diffraction quality protein crystals for structural determination using X-ray crystallography. The first step to achieve protein crystallization is to find out suitable chemical reagents. However, it is not an easy task. Exhausting trial and error tests of numerous combina...
