Restriction digests of the clone give the following sizes (kb): EcoRI--5.2; PstI--5.2; HindIII--2.9, 2.4. Shuttle vector for integrating sequences at leu1. Permits visual detection of recombinants by lacZalpha complementation. Constructed from pJK142 (ATCC 86955) by inserting the leu1 gene at the NdeI site. The leu1 gene contains the following unique restriction sites: StyI EcoNI Eco47III BsmI Bsu36I SplI Tth3I NdeI NruI SnaBI. The order of the major feature in the plasmid is: ampR - pMB1 ori - 5' lacZ' - SacI/MCS/KpnI - 3' lacZ' - leu1. |
