Replacing a cassette of 31 residues from Escherichia coli release factor 1 with the equivalent residues in release factor 2 gave a protein active in codon-specific binding to the ribosome but inactive in peptidyl-tRNA hydrolysis. Such a phenotype is also...

Two of the main problems associated with matrix-assisted laser desorption-ionization time-of-flight (MALDI-TOF) analysis of polymers are mass discrimination and poor reproducibility. This paper shows that the use of binary solvent systems is one of the causes of these problems. It...

trp repressor of Escherichia coli controls transcription initiation in operons involved in tryptophan biosynthesis by binding to operator sequences within the regulated promoters. Naturally occurring operators are homologous over an 18-base pair region and display dyad symmetry. We have examined...

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) with nonpolar matrices has been investigated for its applicability to the characterization of atmospheric resid crude oil fractions. The data obtained by use of nonpolar matrices was compared with that from polar matrices...
