Biological nitrogen fixation is catalyzed by nitrogenase, a complex metalloenzyme composed of two separately purifiable component proteins encoded by the structural genes nifH, nifD, and nifK.… Expand
EFFECT OF LIGNIN CONTENT AND EXTRACTIVES ON THE HIGHER HEATING VALUE OF WOOD
- R. White
As part of a study of the charring rate of wood, I determined the higher heating values (gross heat of combustion) and the chemical composition of samples from four hardwoods and four softwoods. The… Expand
The genome of M. acetivorans reveals extensive metabolic and physiological diversity.
Methanogenesis, the biological production of methane, plays a pivotal role in the global carbon cycle and contributes significantly to global warming. The majority of methane in nature is derived… Expand
Testing and classification of individual plants for fire behaviour: plant selection for the wildland-urban interface
Knowledge of how species differ in their flammability characteristics is needed to develop more reliable lists of plants recommended for landscaping homes in the wildland-urban interface (WUI). As… Expand
Use of the cone calorimeter to detect seasonal differences in selected combustion characteristics of ornamental vegetation
The flammability of living vegetation is influenced by a variety of factors, including moisture content, physical structure and chemical composition. The relative flammability of ornamental… Expand
Mechanism for the desulfurization of L-cysteine catalyzed by the nifS gene product.
The nifS gene product (NIFS) is a pyridoxal phosphate binding enzyme that catalyzes the desulfurization of L-cysteine to yield L-alanine and sulfur. In Azotobacter vinelandii this activity is… Expand
Methanocaldococcus jannaschii uses a modified mevalonate pathway for biosynthesis of isopentenyl diphosphate.
Archaea have been shown to produce isoprenoids from mevalonate; however, genome analysis has failed to identify several genes in the mevalonate pathway on the basis of sequence similarity. A… Expand
Burning rate of solid wood measured in a heat release rate calorimeter
Burning rate is a key factor in modeling fire growth and fire endurance of wood structures. This study investigated the burning rate of selected wood materials as determined by heat release, mass,… Expand
Identification of an archaeal 2-hydroxy acid dehydrogenase catalyzing reactions involved in coenzyme biosynthesis in methanoarchaea.
Two putative malate dehydrogenase genes, MJ1425 and MJ0490, from Methanococcus jannaschii and one from Methanothermus fervidus were cloned and overexpressed in Escherichia coli, and their gene… Expand
(R)-citramalate synthase in methanogenic archaea.
The Methanococcus jannaschii gene MJ1392 was cloned, and its protein product was hyperexpressed in Escherichia coli. The resulting protein was purified and shown to catalyze the condensation of… Expand
