Metabolic evolution of Corynebacterium glutamicum for increased production of L-ornithine.

abstract：BACKGROUND:The antiphospholipid syndrome (APS), characterised by recurrent miscarriage and thrombosis, is a significant cause of morbidity and mortality. Domain I (DI) of human beta 2 glycoprotein I (beta2GPI) is thought to contain crucial antibody binding epitopes for antiphospholipid antibodies (aPL), which are criti...
