Purification and characterization of multiple forms of the pineapple-stem-derived cysteine proteinases ananain and comosain.
Napper AD, Bennett SP, Borowski M, Holdridge MB, Leonard MJ, Rogers EE, Duan Y, Laursen RA, Reinhold B, Shames SL. Napper AD, et al. Biochem J. 1994 Aug 1;301 ( Pt 3)(Pt 3):727-35. doi: 10.1042/bj3010727. Biochem J. 1994. PMID: 8053898 Free PMC article.
A mixture of ananain (EC 3.4.22.31) and comosain purified from crude pineapple stem extract was found to contain numerous closely related enzyme forms. ...Nevertheless, differences were seen between comosain and stem bromelain in amino acid composition and kinetic s …

The cysteine proteinases of the pineapple plant.
Rowan AD, Buttle DJ, Barrett AJ. Rowan AD, et al. Biochem J. 1990 Mar 15;266(3):869-75. Biochem J. 1990. PMID: 2327970 Free PMC article.
Two additional cysteine proteinases were detected only in the stem: these were ananain and a previously undescribed enzyme that we have called comosain. Stem bromelain, fruit bromelain and ananain were shown to be immunologically distinct. ...

The proteolytic system of pineapple stems revisited: Purification and characterization of multiple catalytically active forms.
Matagne A, Bolle L, El Mahyaoui R, Baeyens-Volant D, Azarkan M. Matagne A, et al. Phytochemistry. 2017 Jun;138:29-51. doi: 10.1016/j.phytochem.2017.02.019. Epub 2017 Feb 23. Phytochemistry. 2017. PMID: 28238440
The basic fraction contained previously identified species, i.e. basic bromelain forms 1 and 2, ananain forms 1 and 2, and comosain (MEROPS identifier: C01.027). Furthermore, a new proteolytic species, showing similarities with basic bomelain forms 1 and 2, was discovered …

Removal of necrotic tissue with an ananain-based enzyme-debriding preparation.
Skrabut EM, Hebda PA, Samuels JA, Richards SM, Edmunds T, Cunneen MF, Vaccaro CA, McPherson JM. Skrabut EM, et al. Wound Repair Regen. 1996 Oct;4(4):433-43. doi: 10.1046/j.1524-475X.1996.40407.x. Wound Repair Regen. 1996. PMID: 17309694
The remaining proteolytic activity in the preparation was contributed by a co-purifying homologous cysteine protease comosain. Taken together these two proteases provided a protein purity of greater than 95% as judged by sodium dodecyl sulfate polyacrylamide gel electropho …

Purification and characterization of macrodontain I, a cysteine peptidase from unripe fruits of Pseudananas macrodontes (Morr.) harms (Bromeliaceae).
López LM, Sequeiros C, Natalucci CL, Brullo A, Maras B, Barra D, Caffini NO. López LM, et al. Protein Expr Purif. 2000 Mar;18(2):133-40. doi: 10.1006/prep.1999.1165. Protein Expr Purif. 2000. PMID: 10686143
The N-terminal sequence of macrodontain (by comparison with the N-terminus of 30 plant proteases with more than 50% homology) showed a great deal of sequence similarity to the other pineapple-stem-derived cysteine endopeptidases, being 85.7, 85. 2, and 77.8% identical to comos
