Abstract

The nucleotide sequence of a 6940 bp DNA fragment from Desulfovibrio gigas, containing seven ORFs was determined. ORF-1 encodes a probable lipoprotein having high similarities with lytic transglycosylases. ORF-2 encodes a polypeptide that does not show homologies with proteins deposited in the database, but it contains the consensus pattern of class II aminoacyl-tRNA synthetases. The putative protein encoded by ORF-3 possesses high similarities with universal stress response proteins from the UspA family. Northern blot analysis of ORF-3 shows that it is constitutively and abundantly expressed. ORF-4 encodes a probable helix-turn-helix-containing DNA-binding protein, given the presence of the helix-turn-helix motif, characteristic of this class of proteins. Its N-terminal region has high identity with its counterparts from proteins belonging to the RRF2 family. Northern blot analysis shows that ORF-4 is transcribed as a single mRNA in contrast to its orthologue from Desulfovibrio vulgaris. ORF-5 encodes a putative fusion protein as its N- and C-termini show significant homologies with molybdenum formylmethanofuran dehydrogenase and molybdopterin biosynthesis proteins, respectively. ORF-7 encodes a prokaryotic lipoprotein having ...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
