title: Rescue of first-step-transfer amber mutants by "second-step-transfer-blocked" bacteriophage T5 on an su- strain.
abstract: T5 st0 phages irreversibly blocked in the injection of their second-step-transfer DNA can produce active A1 and A2 proteins which complement first-step-transfer amber mutants infecting an su(-) strain.
