Craig T. Martin and Joseph E. Coleman, Biochemistry 28, 2760-2762, 1989 The study of transcription kinetics by T7 RNA polymerase is facilitated by the small size of its promoter, allowing the use of synthetic oligonucleotide templates with carefully defined sequences. We …

Craig T. Martin, Randall H. Morse, Robert M. Kanne, Harry B. Gray, Bo G. Malmström, Sunney I. Chan, Biochemistry 20, 5147-5155, 1981 The reactions of nitric oxide (NO) with the oxi- dized and reduced forms of fungal and tree laccase, as well as with tree laccase depleted in type 2 copper, are reported. The products of the reactions were determined by NMR and mass spectroscopy, whereas the oxidation states of the enzymes were monitored by EPR and optical spectroscopy. All three copper sites in fungal lacease are reduced by NO. In addition,NO forms a specific complex with the reduced type 2 copper. NO similarly reduces all of the copper sites in tree lacease, but it also oxidizes the reduced sites produced by ascorbate or NO reduction. A catalytic cycle is set up in which N20, …
