# Are there protein-based computational models?

Is there a framework/formalism that defines computational models based on proteins other than Adleman's DNA model or this work by Cherry and Qian?

Edit 2020 (related models/ideas based on DNA):

DNA allows to store large amount of data, it seems to me that the combination of DNA-based memory methods and technologies like CRISPR as computational workers might be an interesting and relevant venue.

As mentioned in the answers, $$\pi$$-calculus and bioambinet calculus are relevant here as well:
