is able to add a carbonyl group to carbon 4 and 4' of the beta carotene molecule.Although functionally identical, several distinct beta-carotene ketolase proteins are known. That is to say they differ from an evolutionary perspective in their primary amino acid/protein sequence. They are different proteins that complete the same function. Thus, bacterial (CrtW) and micro-algal beta-carotene ketolase proteins such as BKT isolated from Haematococcus pluvialis are
