dimer2 was derived from dimer1 with the following mutations: V71A/C117T/F118L/V127T/S131P/A217S
amino acid numbers relative to DsRed. show relative to dimer1
The dimer2 variant possesses many desirable properties, such as a faster and more complete maturation than wild-type DsRed and a greater fluorescent brightness than the fast-maturing mutant DsRed.T1
