PS-CFP Sequence

PS-CFP was derived from aceGFP with the following mutations: T62A/N121S/H148T/K158R/I167V/E172K/F221L/G222E/*237WextKLN

Note: The text of Chudakov et al (2004) describes PS-CFP with the mutation K238Q, but the GenBank Sequence does not. Here, we show the GenBank sequence lacking K238Q

GenBank: AAT01543
