Examples of “subtilisin” in a Sentence

verb

British English

  • The protein was subtilised to analyse its fragments. (Note: 'subtilised' is a rare derived verb from subtilisin.)

American English

  • We subtilized the sample to map the cleavage sites. (Rare derived verb.)

adverb

British English

  • The peptide was cleaved subtilisin-specifically. (Highly contrived, technical jargon.)

American English

  • The bond hydrolysed subtilisin-dependently. (Highly contrived, technical jargon.)

adjective

British English

  • The subtilisin-like protease showed high activity.

American English

  • They studied the subtilisin-type cleavage mechanism.

Common Mistakes When Using “subtilisin”

  • Misspelling as 'subtilsin', 'subtilysin', or 'subtilisen'.
  • Confusing it with 'subtilin', which is a different antibiotic compound.
  • Using it as a general term for any enzyme.

FAQ

Frequently Asked Questions

Yes, the subtilisin used in detergents is engineered and formulated to be safe, effective, and non-irritating in its final product form.

No, it has specificity. It cleaves peptide bonds adjacent to certain amino acids, so its activity depends on the protein's sequence and structure.

It is derived from the Latin name of the bacterium that produces it, Bacillus subtilis.

Primarily as a research tool in laboratories for protein analysis. It is not a common therapeutic drug itself.
