Vibrio cholerae enterotoxin genes: nucleotide sequence analysis of DNA encoding ADP-ribosyltransferase. 1984

H A Lockman, and J E Galen, and J B Kaper

The nucleotide sequence of the DNA encoding the ADP-ribosyltransferase (A1) fragment of cholera enterotoxin was determined. A putative precursor of the A1 peptide contains an 18-amino acid leader peptide, and the mature A1 peptide contains 194 amino acids. The primary structure of the A1 fragment from cholera enterotoxin is more related to that from a human enterotoxigenic Escherichia coli than to that from a porcine enterotoxigenic E. coli.

D009713	Nucleotidyltransferases	A class of enzymes that transfers nucleotidyl residues. EC 2.7.7.	Nucleotidyltransferase
D011065	Poly(ADP-ribose) Polymerases	Enzymes that catalyze the transfer of multiple ADP-RIBOSE groups from nicotinamide-adenine dinucleotide (NAD) onto protein targets, thus building up a linear or branched homopolymer of repeating ADP-ribose units i.e., POLY ADENOSINE DIPHOSPHATE RIBOSE.

D004262	DNA Restriction Enzymes	Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.
