Disease relevance of crtI


High impact information on crtI


Biological context of crtI

  • In this report, we present the DNA and deduced amino acid sequences of the genes encoding these proteins, namely, crtB and crtI, from R. sphaeroides and present evidence for the existence of a crtIB operon [2].

Associations of crtI with chemical compounds

  • The N- and C-termini of these CrtD proteins present a high degree of similarity with the N- and C-termini of other carotenoid dehydrogenases including those encoded by crtI genes [3].

Other interactions of crtI

  • Although the crtI and crtB genes have been sequenced from a number of different organisms, the transcriptional organization and regulation of these genes have not been analyzed in detail [2].
