Asam L-Pyroglutamic (uga dikenal minangka PCA, 5-oxoproline, asam pidolik, utawa pyroglutamate kanggo bentuk dhasar) minangka turunan asam amino alami sing ana ing endi-endi, nanging klompok amino bebas asam glutamat utawa glutamin siklik dadi laktam Iki minangka metabolit ing siklus glutathione sing diowahi dadi glutamat 5-oxoprolinase. Piroglutamate ditemokake ing akeh protein kalebu bakteriorhodopsin. Residu asam glutamat N-terminal lan residu glutamin sacara spontan bisa siklus dadi pyroglutamate, utawa diowahi kanthi enzimatik dening siklut glutaminil. Iki minangka salah sawijining wujud N-termini sing diblokir sing dadi masalah kanggo urutan N-terminal nggunakake kimia Edman, sing mbutuhake klompok amino primer gratis sing ora ana ing asam pyroglutamic. Enzim pyroglutamate aminopeptidase bisa mulihake N-terminus gratis kanthi ngilangi residu piroglutamat.

Asam L-Pyroglutamic CAS: 98-79-3 Introduction
Asam piroglutam (uga dikenal minangka PCA, 5-oxoproline, asam pidolic, utawa pyroglutamate kanggo bentuk dhasar) minangka turunan asam amino alami sing ana ing endi-endi nanging ing endi klompok amino bebas asam glutamat utawa glutamin nyipta laktam.
Iki minangka metabolit ing siklus glutation sing diowahi dadi glutamat karo 5-oxoprolinase.
Pyroglutamate ditemokake ing akeh protein kalebu bakteriorhodopsin. Residu asam glutamat N-terminal lan residu glutamin sacara spontan bisa siklus dadi pyroglutamate, utawa diowahi kanthi enzimatik dening siklut glutaminil. Iki minangka salah sawijining wujud N-termini sing diblokir sing dadi masalah kanggo urutan N-terminal nggunakake kimia Edman, sing mbutuhake klompok amino primer gratis sing ora ana ing asam pyroglutamic. Enzim pyroglutamate aminopeptidase bisa mulihake N-terminus gratis kanthi ngilangi residu piroglutamat.
