Phe residues

WebWe would like to show you a description here but the site won’t allow us. WebThis set of Phe residues cannot be interchanged with the Phe residues found in canonical red/green CBCRs such as NpR6012g4. Our results provide new insights into the flexible protein–chromophore interactions used by CBCRs to generate their remarkable spectral diversity.
