Renatured (Comment) | Organism |
---|---|
when renatured after treatment with 6.0 M guanidine hydrochloride 80 to 90% of the original activity regained, renaturation of isolated alpha subunits leads to a lower recovery of activity, 65%, which is increased by about 30% in presence of an equivalent amount of beta subunit | Bacillus subtilis |
