What is "exosite"

n. (context biochemistry English) A secondary binding site, remote from the active site, on a protein

An exosite is a secondary binding site, remote from the active site, on an enzyme or other protein.

This is similar to allosteric sites, but differs in the fact that, in order for an enzyme to be active, its exosite typically must be occupied. Exosites have recently become a topic of increased interest in biomedical research as potential drug targets.

Exosite is an Internet of Things (IoT) software as a service company that develops software for companies that view and analyze data collected from sensors built into physical objects. It is headquartered in Minneapolis, Minnesota with additional offices in Taiwan, Hungary and Texas. Hans Rempel, Troy Kopischke and Danny Cunagin founded the company in 2009 and Rempel is Exosite's chief executive officer. The company held a $2 million series A funding round in 2012.

In 2014, the company partnered with Texas Instruments to offer its cloud-based IoT platform on Texas Instruments' LaunchPad series microcontrollers.
