Rabbits were immunized with electrophoretically pure catalase from Staphylococcus aureus ATCC 12 600. The antiserum was used to study whether S. aureus subsp. anaerobius was able to synthesize the apoprotein of catalase. Proteins were separated on polyacrylamide gels (SDS-PAGE) and transferred to nitrocellulose membranes and were detected by immunoblotting. No protein reacting with the purified immunoglobulins against S. aureus ATCC 12,600 catalase could be detected in crude and partially purified cellular extracts from S. aureus subsp. anaerobius or its aerotolerant mutants.

Acatalasemia was one of the earliest described genetic enzyme defects. In 1990, a causal point mutation (a splicing mutation) was first reported in a Japanese patient with acatalasemia. In the present study, the polymerase chain reaction and single-strand conformation polymorphism analysis were used to determine whether the same point mutation was present in unrelated Japanese patients. The subjects studied were the previously examined acatalasemic female, her brother, who is hypocatalasemic, and two other unrelated acatalasemic patients. A single G to A point mutation at the fifth position of intron 4, identical to that previously found, was present in all the studied patients. This finding strongly suggests that only a single mutated allele has spread in the Japanese population.
