Canada temple cancels event over 'imminent threat'

The Brampton Triveni temple in Canada has cancelled a consular event after the Canadian police warned them of an "extremely high and imminent" threat level of violent protests. The Life Certificate event, organised by the Consulate General of India, Toronto, was scheduled for November 17 at the temple premises. The cancellation comes almost a week after protestors carrying Khalistani flags clashed with devotees at a Hindu Sabha temple and disrupted an event co-organised by the temple authorities and the Indian Consulate at Brampton. India condemned the attack and called for the prosecution of those involved. Relations between India and Canada have been strained since Prime Minister Justin Trudeau's allegations in September last year of a potential involvement of Indian agents in Khalistan extremist Hardeep Singh Nijjar's killing.

The Escherichia coli cellulose synthase subunit G (BcsG) is a Zn2+-dependent phosphoethanolamine transferase [Glycobiology and Extracellular Matrices]

Bacterial biofilms are cellular communities that produce an adherent matrix. Exopolysaccharides are key structural components of this matrix and are required for the assembly and architecture of biofilms produced by a wide variety of microorganisms. The human bacterial pathogens Escherichia coli and Salmonella enterica produce a biofilm matrix composed primarily of the exopolysaccharide phosphoethanolamine (pEtN) cellulose. Once thought to be composed of only underivatized cellulose, the pEtN modification present in these matrices has been implicated in the overall architecture and integrity of the biofilm. However, an understanding of the mechanism underlying pEtN derivatization of the cellulose exopolysaccharide remains elusive. The bacterial cellulose synthase subunit G (BcsG) is a predicted inner membrane–localized metalloenzyme that has been proposed to catalyze the transfer of the pEtN group from membrane phospholipids to cellulose. Here we present evidence that the C-terminal domain of BcsG from E. coli (EcBcsGΔN) functions as a phosphoethanolamine transferase in vitro with substrate preference for cellulosic materials. Structural characterization of EcBcsGΔN revealed that it belongs to the alkaline phosphatase superfamily, contains a Zn2+ ion at its active center, and is structurally similar to characterized enzymes that confer colistin resistance in Gram-negative bacteria. Informed by our structural studies, we present a functional complementation experiment in E. coli AR3110, indicating that the activity of the BcsG C-terminal domain is essential for integrity of the pellicular biofilm. Furthermore, our results established a similar but distinct active-site architecture and catalytic mechanism shared between BcsG and the colistin resistance enzymes.
