Musa accuminata is the member of family Musaceae. The fruits of M. accuminata are harvestedin unriped green in order to better withstand transportation and to slow down the natural ripening processbecause of several weeks travel from the production areas to the end markets. The ripening process is amulti step reaction involves a number of complex enzymes. The present work is aimed to computationalcharacterization of these ripening enzymes in order to understand the ripening mechanism. In this workidentification of the enzymes/proteins involved in ripening process are characterized by their conserveddomains (conserved, 3-dimension region). The domains are identified by using the computational tool,CDART (Conserved Domain Architecture Retrieval Tool). By using this applied approach a number ofconserved domains were identified, out of these enzymes, the domain pattern of Aspartate aminotransferase(AAT_Like), Glycosyl hydrolase (Glyco_Hydr) and oxoglutarate (20G_Fe) were reported themost conserved followed by Ethylene insensitive (EIN3), GT1, DPBB & Pollen in ripening enzymecomplexes. The data, thus, obtained provide new insights in order to understand the role of the proteinsplaying in different stages of ripening process. These results provide a basis for further studies on themolecular mechanism of ripening process and food technological applications for delayed ripening in fruits,where ripening proteins plays an important role in.
