Meaning and Definition

A biochemical process where a peptide bond is transferred from one molecule to another.

In biochemistry and medicine, specifically referring to the reaction catalyzed by transpeptidase enzymes, crucial for processes like bacterial cell wall synthesis. It describes the transfer of a peptide segment.

  • Using it as a verb (e.g., 'it transpeptidates'); the verb is 'transpeptidate', which is even rarer.

FAQ

Frequently Asked Questions

Transpeptidation is the chemical process or reaction. Transpeptidase is the enzyme that catalyzes (carries out) that reaction.

No, it is a highly specialized scientific term not encountered in everyday language or even in most general academic writing outside specific life science fields.

It is a critical target for antibiotics. Drugs like penicillins and cephalosporins inhibit bacterial transpeptidases, preventing cell wall synthesis and killing the bacteria.

While humans have enzymes that form peptide bonds (like in protein synthesis), the specific 'transpeptidation' referred to by this term is predominantly discussed in the context of bacterial physiology, making it a key point for selective antibiotic action.

A biochemical process where a peptide bond is transferred from one molecule to another.

Transpeptidation is usually technical/scientific in register.

Transpeptidation: in British English it is pronounced /ˌtrænzˌpep.tɪˈdeɪ.ʃən/, and in American English it is pronounced /ˌtrænzˌpep.təˈdeɪ.ʃən/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think 'TRANSfer of a PEPTIDE' + '-ATION' (a process). It's the process of moving a peptide bond.

Conceptual Metaphor

A RELAY RACE where a peptide baton is passed from one runner (molecule) to another.
