The biological Claisen condensation catalyzed by [beta]-ketothiolase from Zoogloea ramigera
(Massachusetts Institute of Technology, 1989)
Electron transfer and protein engineering studies of the soluble methane monooxygenase from Methylococcus capsulatus (Bath)
(Massachusetts Institute of Technology, 2003)
Chapter 1. Introduction: Electron Transfer in Biological Systems In many biological processes, including oxidative phosphorylation and photosynthesis, electron transfer reactions play vital roles. Electrons must be transported ...
Mechanistic studies of the Class I ribonucleotide reductase from Escherichia coli
(Massachusetts Institute of Technology, 2006)
Ribonucleotide reductases (RNRs) catalyze the conversion of nucleotides to deoxynucleotides, providing the monomeric precursors required for DNA replication and repair. The class I RNRs are found in many bacteria, DNA ...
An approach to the technetium labelling of proteins
(Massachusetts Institute of Technology, 1984)
Molecular oxygen adsorbates at a Au/Ni(111) surface alloy and their role in catalytic CO oxidation at 70 - 250 K
(Massachusetts Institute of Technology, 2006)
Oxygen is observed to adsorb molecularly on 0.13 - 0.27 ML Au/Ni(1 111) surface alloys at 77 K, in stark contrast to dissociative adsorption on Ni and no adsorption on Au surfaces. Molecular 02 adsorbates on the Au/Ni(111) ...
Polymers for electronics and chemical sensing applications
(Massachusetts Institute of Technology, 2006)
The incorporation of molecular structures such as shape persistent molecular frameworks, strong hydrogen bond donor groups or perfluoro-alkyl groups can result in considerable gains in the performance of some established ...
Structures of oxalate oxidoreductase : C₂ activation by a microbial TPP-dependent ferredoxin oxidoreductase
(Massachusetts Institute of Technology, 2015)
Oxalic acid is a two-carbon diprotic acid that is toxic to humans. In large doses, it can cause death by poisoning, and in smaller doses over time it can lead to chronic renal disease, such as the formation of kidney stones, ...
Structural studies of allosteric regulation in the class Ia Ribonucleotide reductase from Escherichia coli
(Massachusetts Institute of Technology, 2013)
Ribonucleotide reductase (RNR) converts ribonucleotides to deoxyribonucleotides, the building blocks for DNA replication and repair. The E. coli class Ia enzyme requires two subunits to catalyze the radical-based reduction ...
Snapshots of radical enzyme catalysis : the crystal structures of biotin synthase and lysine 5,6-aminomutase
(Massachusetts Institute of Technology, 2004)
(cont.) in the same pathway. To further probe the relationship of the adenosylmethionine and adenosylcobalamin-dependent radical enzymes, the crystal structure of lysine 5,6-aminomutase was determined to 2.8 [angstroms] ...
Catalytic enantioselective synthesis of oxindoles and benzofuranones bearing a quaternary stereocenter and reactions of palladium bisphosphine complexes relevant to catalytic C-C bond formation
(Massachusetts Institute of Technology, 2004)
In Part I the development of a new method for the construction of oxindoles and benzofuranones bearing quaternary stereocenters is discussed. A planar-chiral PPY derivative catalyzes the O-to-C acyl group migration (Black ...
