3.4.22.2 | hexadecyltrimethyl ammonium bromide | the presence of hexadecyltrimethyl ammonium bromide allows 41% recovery of enzymatic activity of acid-unfolded papain in the presence of hexadecyltrimethyl ammonium bromide the enzyme exists as a compact intermediate with regain of native-like secondary and partial tertiary structure as well as high 8-anilino-1-naphthalene-sulfonic acid binding with the partially recovered enzymatic activity | Carica papaya |
3.4.22.2 | SDS | the presence of SDS allows 43% recovery of enzymatic activity of acid-unfolded papain, addition of 8 mM SDS results in the loss of 8-anilino-1-naphthalene-sulfonic acid binding sites exhibited by a decrease in 8-anilino-1-naphthalene-sulfonic acid fluorescence intensity, suggesting the burial of hydrophobic patches, papain at low pH and in the presence of SDS exists in a partially folded state characterized by native-like secondary structure and tertiary folds | Carica papaya |
3.4.22.2 | Tween | the presence of Tween-20 allows 39% recovery of enzymatic activity of acid-unfolded papain in the presence of Tween-20, acid-unfolded papain exists as a compact intermediate with molten-globule-like characteristics | Carica papaya |

the activity of papain is reduced to 35% at pH 2 and in the absence of detergents, at pH 2 papain exhibits a substantial amount of secondary structure and is relatively less denatured compared with 6 M guanidine hydrochloride but loses the persistent tertiary contacts of the native state | Carica papaya |
