Linkage of reduced receptor affinity and superinfection to pathogenesis of TR1.3 murine leukemia virus.

abstract：:Measles virus has two glycoproteins. The larger glycoprotein (HA) is composed of 76,000-dalton subunits that are bound by disulfide bonds. The smaller glycoprotein (F) appears to contain a glucosamine-rich portion that is linked to an unglycosylated protein by disulfide bonds. ...
