The nucleotide sequence of the 1794-bp fragment containing the crtD gene from Rhodobacter sphaeroides 2.4.1 encoding for methoxyneurosporene dehydrogenase has been determined. A 63% sequence identity was found when compared with the nucleotide sequence of the crtD gene from Rhodobacter capsulatus. A putative regulatory palindromic motif present in the crtD gene from R. capsulatus also exists in this gene from R. sphaeroides. The translated open reading frame of the crtD gene of R. sphaeroides has identified a polypeptide of 495 amino acids which shares a 56% sequence identity with the same CrtD protein of R. capsulatus. 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. This is in good agreement with the previously hypothesized homology between CrtI and CrtD proteins.

UI MeSH Term Description Entries
D008969 Molecular Sequence Data Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories. Sequence Data, Molecular,Molecular Sequencing Data,Data, Molecular Sequence,Data, Molecular Sequencing,Sequencing Data, Molecular
D010088 Oxidoreductases The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9) Dehydrogenases,Oxidases,Oxidoreductase,Reductases,Dehydrogenase,Oxidase,Reductase
D002338 Carotenoids The general name for a group of fat-soluble pigments found in green, yellow, and leafy vegetables, and yellow fruits. They are aliphatic hydrocarbons containing 4 terpene subunits. Carotenes,Carotenoid,Tetraterpene Derivatives,Tetraterpenes,Carotene,Derivatives, Tetraterpene
D003062 Codon A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (CODON, TERMINATOR). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, TRANSFER) complementary to all codons. These codons are referred to as unassigned codons (CODONS, NONSENSE).

D000595 Amino Acid Sequence The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.
