Abstract
|
|
|
|
In this study, we examined low molecular weight peptides using proteomics in order to identify their original proteins, derive their peptides, and determine the functions of the proteins in Tenebrio molitor, the mealworm (larvae, pupae, or adult) from which the peptides were extracted. Fifty-four proteins were finally identified through an analysis of proteome to derive the analyzed peptides. The proteins that induced low molecular weight peptides were identified to be the most abundant in adults only, and the next highest were derived from a group containing both adults and larva. However, other groups, including pupa, were detected to have a lower frequency of peptides. As a result of orthologous classification of the detected proteins, the general function prediction was only investigated at the highest frequency among the examined proteins. Proteins related to chromatin structure and dynamics were detected by their higher frequency among functional classes. The next highest frequency was shown by proteins related to amino acid transport and metabolism and carbohydrate transport and metabolism. Therefore, it is assumed that proteins correlated with chromatin, amino acid, and carbohydrate metabolisms are easily induced into low molecular weight peptides, and that their peptides could play a role as bioactive substances.
