Comparison of the impact of ships to size-segregated particle concentrations in two harbour cities of northern Adriatic Sea.

Detailed information on in-harbour shipping contribution to size segregated particles in coastal cities are scarce, especially in the busy Mediterranean basin. This poses issues for human exposure and air quality in urban harbour agglomerates, where only criteria pollutants (i.e.

Crystal structure of a eukaryotic (pea seedling) copper-containing amine oxidase at 2.2 A resolution.

Background: Copper-containing amine oxidases catalyze the oxidative deamination of primary amines to aldehydes, in a reaction that requires free radicals. These enzymes are important in many biological processes, including cell differentiation and growth, would healing, detoxification and signalling. The catalytic reaction requires a redox cofactor, topa quinone (TPQ), which is derived by post-translational modification of an invariant tyrosine residue.

Purification, crystallization and preliminary X-ray crystal structure analysis of copper amine oxidase from Arthrobacter globoformis.

beta-Phenylethylamine oxidase from the Gram-positive bacterium Arthrobacter globoformis has been crystallized as three crystal forms. Two belong to space group C2 and one to space group P2(1)2(1)2(1), respectively. The unit-cell volumes are consistent with one infunit of 70 644 Da per asymmetric unit for the two monoclinic forms, and with two infunits per asymmetric unit for the orthorhombic crystals.
