Researchers have created a special enzyme that can shear off the substances on red blood cells that are responsible for potentially fatal immune reactions if a patient receives the wrong type of blood, according to a new study. The enzyme is not yet effective enough to allow for large-scale processing to convert type A or type B blood into type O, said lead author David Kwan, a postdoctoral fellow of chemistry at the University of British Columbia's Centre for Blood Research in Vancouver, Canada. "We're not there yet. This is really a step towards that," Kwan said. "The big thing is that we've shown that it's feasible to improve these enzymes."
