in vivo studies of ssb-113 strains carrying the cloned ssb-113 gene in psc101 have shown that overproduction of the mutant protein does not complement the temperature-sensitive conditional lethality caused by the ssb-113 mutation when present in single gene copy in contrast to effects recently observed in ssb-1 strains overproducing the ssb-1 encoded protein ( chase , j. w. , murphy , j. b. , whittier , r. f. , lorensen , e. , and sninsky , j. j . ( 1983 ) j. mol . biol . 164 , 193-211 ) .
