The plasmid pIP231, determining tetracycline resistance and hydrogen sulfide production is shown to belong to incompatibility group Y and to code for a restriction and modification system. Unlike the IncY plasmids, P7 and P15B, plasmid pIP231 shows only little genetic and physical homology with P1 p

โฆ Synopsis
Two regions tentatively called unsA and unsR were identified on pSC101. One, unsA, corresponds to less than 650 bp of the N-terminal in the tetracycline resistance structural gene and seems to inhibit stable maintenance of pSC101. The other, unsR, is defined within the 1 kb XhoI-EcoRI region located upstream of the tetracycline resistance structural gene and is a regulatory gene clearly distinct from tetR (Unger et al. 1984); it serves as a suppressor of the unsA function.

## Abstract P2PโR is the alternately spliced product of the P2PโR/PACT gene in that P2PโR lacks one exon encoding 34 amino acids. The 250 kDa P2PโR protein is the predominate product expressed in multiple murine cell lines. It is a highly basic protein that contains multiple domains including an Nโ
