DOI: 10.1002/cctc.202400769
Abstract: The GT99 domain of the membrane‐anchored WbbB glycosyltransferase (WbbBGT99) catalyzes the transfer of 3‐deoxy‐D‐manno‐oct‐2‐acid (β‐Kdo) to an O‐antigen saccharide acceptor with retention of stereochemistry. It has been proposed that the enzyme follows an unprecedented double‐displacement… read more here.

Abstract: Abstract Cis-[Ru(bpy)2(OH2)2](OTf)2 (1·(OTf)2; OTf− = CF3SO3−) was reacted with 2-picolinamide (H2pia) in EtOH to form bis-heteroleptic complex [Ru(bpy)2(H2pia)]X2 (2·X2; X− = OTf− or Cl−). Crystal structures of 2·X2 revealed that H2pia was coordinated to Ru(II) through N of pyridyl… read more here.
