2. (biochemistry) A biomolecule that catalyses a biological chemical reaction: either a globular protein with this function or an RNA molecule with this function.

   Hypernym: biocatalyst

   Hyponym: ribozyme

   2. (strictly) The protein type specifically.

      Hypernym: biocatalyst

      Hyponym: see list

3. (Christianity) Leavened bread, as opposed to azyme.

Before 1980, protein enzymes were the only known type, so the word enzyme invariably meant that type. Since RNA catalysis was discovered, ribozymes are often viewed as a type of enzyme (in the newer and broader sense of the word), but even today, their name is often used coordinately with the stricter sense.
