Molecular structure of trimethylamine dehydrogenase from the bacterium W3A1 at 6.0-A resolution.
An electron density map of trimethylamine dehydrogenase has been calculated at 6.0-A resolution. Protein phases were based on two isomorphous mercury derivatives with similar binding properties, and on anomalous scattering measurements. The map has been averaged about the noncrystallographic 2-fold axis, plotted on transparent sheets and used to construct a wooden model. The elipsoidal dimer ha...
متن کاملStabilization mechanism of cytochrome c552 from a moderately thermophilic bacterium, Hydrogenophilus thermoluteolus.
Cytochrome c(552) (PH c(552)) from moderately thermophilic Hydrogenophilus thermoluteolus exhibits stability intermediate between those of cytochrome c(552) (HT c(552)) from thermophilic Hydrogenobacter thermophilus and cytochrome c(551) (PA c(551)) from mesophilic Pseudomonas aeruginosa. To understand the mechanism of stabilization of PH c(552), we introduced mutations into PH c(552) at five s...
متن کاملFactors affecting the production of pyrroloquinoline quinone by the methylotrophic bacterium W3A1.
Two variants of the methylotrophic bacterium W3A1, designated W3A1-S (slimy) and W3A1-NS (nonslimy), were compared with respect to their ability to grow in batch culture on the C1 substrates methylamine, methanol, and trimethylamine. Substrate utilization, cell density, pH, cellular and soluble polysaccharide production, and concentrations of the enzymes methylamine dehydrogenase, trimethylamin...
متن کاملPurification and properties of methylamine dehydrogenase from Paracoccus denitrificans.
Methylamine dehydrogenase from Paracoccus denitrificans was purified to homogeneity in two steps from the periplasmic fraction of methylamine-grown cells. The enzyme exhibited a pI value of 4.3 and was composed of two 46,700-dalton subunits and two 15,500-dalton subunits. Each small subunit possessed a covalently bound pyrrolo-quinoline quinone prosthetic group. The amino acid compositions of t...
متن کاملCloning and gene expression of cytochrome P450 gene from Alcanivorax borkumensis Bacterium
Alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. The ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. A. borkumensis have two genetic systems for alkane biodegradation. The First system is alkane hydroxylase (alk-B1and alk-B2) and the second system is...
