Kithmie MalagodaPathiranage, Ruptanu Banerjee, and Craig T. Martin, Nucleic Acids Research, 52(17), 10607-10618. 2024 Current approaches to RNA synthesis/manufacturing require substantial (and incomplete) purification post-synthesis. We have previously demonstrated the synthesis of RNA from a complex in which T7 RNA polymerase …
Kithmie MalagodaPathiranage and Craig T. Martin, Methods in Enzymology, 691, 209-222, 2023 T7 RNA polymerase is widely used to synthesize RNA of any length, and long-standing protocols exist to efficiently generate large amounts of RNA. Such synthesis, however, is often plagued …

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, …
