Major artists of the Venetian school

Page 52

Venetian painting was a major force in Italian Renaissance painting and beyond. Beginning with the work of Giovanni Bellini and his brother Gentile Bellini and their workshops, the major artists of the Venetian school included Giorgione, Titian, Tintoretto (1518–1594), Paolo Veronese (1528–1588) and Jacopo Bassano (1510–1592) and his sons. Considered to give primacy to colour over line, the tradition of the Venetian school contrasted with the Mannerism prevalent in the rest of Italy. The Venetian style exerted great influence upon the subsequent development of Western painting.

In molecular biology, the HdeA family of proteins is a stress response protein family found in highly acid resistant bacteria such as Shigella flexneri and Escherichia coli, but which is lacking in mildly acid tolerant bacteria such as Salmonella. HdeA is one of the most abundant proteins found in the periplasmic space of E. coli, where it is one of a network of proteins that confer an acid resistance phenotype essential for the pathogenesis of enteric bacteria. HdeA is thought to act as a chaperone, functioning to prevent the aggregation of periplasmic proteins denatured under acidic conditions. The HNS protein, a chromatin-associated protein that influences the gene expression of several environmentally-induced target genes, represses the expression of HdeA. HdeB, which is encoded within the same operon, may form heterodimers with HdeA. HdeA is a single domain protein with an overall fold that is similar to the fold of the N-terminal subdomain of the GluRS anticodon-binding domain.
