Isicelo

I-Fmoc-L-methionine ivame ukusetshenziswa ku-biochemistry, ikakhulukazi ekuhlanganiseni kwama-polypeptides. Ngaphezu kwalokho, i-Fmoc-L-methionine iyi-amino acid enephuzu le-isoelectric, edinga ukulungiswa ngokucophelela kwe-pH yesistimu yokusabela ukuze kuzuzwe ifomu lomkhiqizo olifunayo.

Ukuphepha

Amakhodi Engozi 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yezokuphepha S22 - Ungaluphefumuli uthuli.
I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
I-S36/37/39 - Gqoka izingubo zokuzivikela ezifanele, amagilavu nokuvikela iso/ubuso.
S27 - Khumula ngokushesha zonke izingubo ezingcolile.
S26 - Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
