Misc.Comments : pT181 occurs naturally in staphylococcus aureus and encodes inducible resistance to tetracycline. it contains four open reading frames encoding four putative polypeptides a, 37.5 kda; b, 35 kda; c, 23 kda, and d, 18 kda [3]. polypeptide a is the repc protein [2] (bases 3563-557). polypeptides b and d (bases 2595-3482 and 2180-2638, respectively) are involved in tetracycline resistance [3]. there is no known function for polypeptide c and deletion of a large portion of it causes no noticeable changes [3]. Replication, originating in a 168 bp span, proceeds unidirectionally and clockwise (anticlockwise as the map is conventionally drawn) [2].
