How are CheY, CheA, CheW, CheZ pronounced in speech? This is a quick followup question to this question about proteins that play important roles in chemotaxis: How does one pronounce the protein names "CheY", "CheW", etc., in English? My guess would be that they're pronounced like "key why", "key double-u", etc. (I want to refer to these proteins in a philosophy of science presentation, but don't have much background in molecular biology. I know about chemotaxis only from reading.)

As was mentioned in the comments, these are not real words and there is no authority on their pronunciation. Given that Che is an abbreviation of chemotaxis, I would pronounce it the same as key.
