| Abstract: | The gene encoding for aspartate transcarbamoylase (ATCase) from Psychrophilicvibrio, strain 2693 was cloned and sequenced. The sequence revealed the existence oftwo gene encoding respectively for a catalytic chain (pyrB) and a regulatory chain(pyr I). The catalytic and regulatory polypeptide chains of Vibrio 2693 ATCase areencoded by a single pyrBI bicistronic operon, and appear to be transcribed under thecontrol of the same promoter. The 3' -terminus of the catalytic cistron (pyrB) isadjacent to the. 5'-terminus of the regulatory cistron, these is only a 4 bp spacebetween the two coding regions. |
