Common Name2,3-bis[(3R)-3-hydroxymyristoyl]-α-D-glucosaminyl 1-phosphate
Description2,3-bis((3R)-3-Hydroxymyristoyl)-alpha-D-glucosaminyl 1-phosphate is an intermediate in Lipid IVA synthesis which is essesntial for the production of LPS. Lipopolysaccharide (LPS), a major outer membrane component, is composed of three domains: Lipid A, the core, which is an oligosaccharide consisting of an inner and outer region; and a distal repeating unit known as the O-antigen. Lipid A is linked to a beta-1,6-linked glucosamine disaccharide. Attached to this is the inner core containing at least two 3-deoxy-D-manno-octulosonate (KDO) units followed by two units of heptose. The outer core region and the O-antigen are attached to one of the heptose units. For some time it was thought that the minimum structure for cell viability in E. coli had the di-Kdo moiety, but viable mutants lacking Kdo and with the basic tetra-acyl form of lipid A, i.e. lacking the two secondary acyl groups (and termed 'lipid IVA'), have recently been produced. Indeed, lipid IVA may be the minimum structure required for the viability of E. coli.
