Part of a large protein helps in preventing aggregation of many other proteins
What is it about?
Proteins when heated or exposed to extreme physical or chemical forces tend to denature and aggregate and becomes non-functional. Large proteins are made of smaller folded parts called domains. One domain of the protein named L-asparaginase was isolated out. This domain was then added to different proteins which were heated or denatured. It was found that the heated protein were protected from undergoing aggregation in the presence of the isolated domain, thus working as a chaperone.
Why is it important?
Many industrial and therapeutic proteins undergo aggregation during storage or transportation or even due to their normal short shelf life. The use of the protein domain reported in our study will prove useful for extending the life of other vulnerable proteins.
