Abstract of the Disclosure Novel DNA constructs comprising regulatory regions plus the structural coding region for hepatitis B surface antigen (HBsAg) are disclosed. The regulatory regions employed are responsive to methanol, non-catabolite repressing carbon sources and catabolite repressing carbon sources followed by carbon source starvation. The novel constructs are incorporated into a variety of linear and circular plasmids. Such plasmids are used to transform suitable hosts and ultimately used for the production and isolation of hepatitis B surface antigen in high yields.
