Reading terminal acetylation and amidation
Terminal acetylation and amidation: Does the name allow both chain termini to be reconstructed?
Source editorial review:
Before interpreting the result
Does the name allow both chain termini to be reconstructed?
- Record N-terminal and C-terminal modifications separately.
- Distinguish covalent acetylation from acetate as a counterion.
- Check whether the reference studied one modification or both.
Terminal acetylation and amidation
A chain's chemical termini belong to the material's complete name. Acetylation and amidation describe specific modifications; omitting them can combine distinct preparations under one letter sequence. Verify their presence in specifications and relevant analytical evidence rather than inferring them from customary short-name usage.
A reading case: what to check
If a paper omits terminal details while a catalog specifies them, mark correspondence as unresolved until clarified. Compare results only within the justified scope. Avoid automatically assigning improved stability or activity to every terminal modification: the property must have been evaluated for that structure and system.
What to preserve in the record
An omitted abbreviation can change material identity. Do not add effects of separately modified termini to predict a variant containing both.
