  1. a Values shown are means of at least two biological replicates, with error in the last digit denoted parenthetically.
  2. b Extracellular activity divided by the activity from an equivalent fraction of lysed culture.
  3. c Activity measured using intact cells divided by the activity from an equivalent fraction of lysed culture.
