Comparative direct infusion ion mobility mass spectrometry profiling of Thermus thermophilus wild-type and mutant ∆cruC carotenoid extracts.

Abstract excerpt

The major carotenoid species isolated from the thermophilic bacterium Thermus thermophilus HB27 have been identified as zeaxanthin-glucoside-fatty acid esters (thermozeaxanthins and thermobiszeaxanthins). Most of the genes of the proposed T. thermophilus carotenoid pathway could be found in the genome, but there is less clarity about the genes which encode the enzymes performing the final carotenoid glycosylation...
