Editing Protein design (section)

===Other applications ===

One of the most desirable uses for protein design is for [[biosensor]]s, proteins that will sense the presence of specific compounds. Some attempts in the design of biosensors include sensors for unnatural molecules including [[TNT]].<ref>{{cite journal |last1=Looger |first1=Loren L. |last2=Dwyer |first2=Mary A. |last3=Smith |first3=James J. |last4=Hellinga |first4=Homme W. |name-list-style=amp |year=2003 |title=Computational design of receptor and sensor proteins with novel functions |journal=[[Nature (journal)|Nature]] |pmid=12736688 |volume=423 |issue=6936 |pages=185–190 |doi=10.1038/nature01556 |bibcode= 2003Natur.423..185L|s2cid=4387641 }}</ref> More recently, Kuhlman and coworkers designed a biosensor of the [[p21 activated kinase|PAK1]].<ref>{{cite journal|last=Jha|first=RK|author2=Wu, YI |author3=Zawistowski, JS |author4=MacNevin, C |author5=Hahn, KM |author6= Kuhlman, B |title=Redesign of the PAK1 autoinhibitory domain for enhanced stability and affinity in biosensor applications.|journal=Journal of Molecular Biology|date=October 21, 2011|volume=413|issue=2|pages=513–22|pmid=21888918|doi=10.1016/j.jmb.2011.08.022 |pmc=3202338}}</ref>

In a sense, protein design is a subset of [[circuit design|battery design]].{{Explain|date=April 2022}}
