Bacillus subtilis Vegetative Catalase Is an Extracellular Enzyme

PMCID: PMC1388663  PMID: 16535198

Abstract

Strong catalase activity was secreted by Bacillus subtilis cells during stationary growth phase in rich medium but not in sporulation-inducing medium. N-terminal sequencing indicated that the secreted activity was due to the vegetative catalase KatA, previously considered an endocellular enzyme. Extracellular catalase protected B. subtilis cells from oxidative assault.
