themselves post-translationally from the precursor protein via protein splicing. Since their …

Metal effect on intein splicing: A review

S Panda, A Nanda, SS Nasker, D Sen, A Mehra… - Biochimie, 2021 - Elsevier
Inteins are intervening polypeptides that interrupt the functional domains of several
important proteins across the three domains of life. Inteins excise themselves from the …

The crystal structure of the naturally split gp41‐1 intein guides the engineering of orthogonal split inteins from cis‐splicing inteins

HM Beyer, KM Mikula, M Li, A Wlodawer… - The FEBS …, 2020 - Wiley Online Library

Conditional protein splicing switch in hyperthermophiles through an intein-extein partnership

CW Lennon, M Stanger, NK Banavali, M Belfort - MBio, 2018 - Am Soc Microbiol
Inteins are intervening proteins that undergo an autocatalytic splicing reaction that ligates
flanking host protein sequences termed exteins. Some intein-containing proteins have …

Substrate specificities of inteins investigated by QuickDrop‐cassette mutagenesis

JS Oeemig, HM Beyer, AS Aranko, J Mutanen… - FEBS …, 2020 - Wiley Online Library
Inteins catalyze self‐excision from host precursor proteins while concomitantly ligating the
