Abstract
Two novel linear DNA plasmids are described. Also, novel fragments of the plasmids containing the autonomous replication sequence (ARS), and thus capable of self-maintenance as extra chromosomal elements are provided. These novel DNA sequences of the present invention are useful in a vector for self-maintenance in Pichia pastoris and are also useful as plasmid vectors which can be shuttled between yeast and bacteria.
