Table 1.

Activity of 70S ribosomes reconstituted from Po cores with L7/L12:Cys99

L7/L12 variant added Activity
Po 3.5
Po + L7/L12:Cys 99 - reduced 12.5
Po + L7/L12:Cys 99 - oxidized 12.9

Results represent Phe/70S particle/15 min in poly[U]-directed polyphenylalanine synthesis (11) (average of three different experiments; SD was <10%). Six equivalents of each indicated protein were added to the Po cores.
