- E. coli cytochrome b562: the entire culture turns red upon overexpression.
- The bilin-binding protein of Pieris brassicae is a blue protein,
although its chromophore biliverdin IXgamma only occurs in insects.
- The neutrophil gelatinase-associated lipocalin (NGAL) is wine-red
if produced in the periplasm of E. coli where it takes up the
endogenous siderophore Fe-enterobactin.
If you need references, just let me know.

Hello CCP4 folks!
I have a quick question - could you suggest a few naturally intensely
colored proteins? Colors based on small molecule co-factors (i.e. metal
ions, flavonoids, etc.) are perfectly fine for my needs :)
I already looked into GFP and its relatives, (bacterio)rodopsin,
azurins/pseudoazurins, and hemoglobins - but I would appreciate more
examples.
I am sure there's a nice review out there somewhere but so far I've not
found it.
Thank you,
Artem
