title: A new mini-transposon for in vivo protein epitope tagging: application to Burkholderia multivorans.
abstract: A short amino acid sequence coding for the mature Pseudomonas aeruginosa OprI lipoprotein was fused to a mini-Tn5 plasposon (mini-transposon with an origin of replication) with tetracycline resistance in order to generate in-frame fusion proteins after transposition. After conjugative transfer to Burkholderia multivorans, clones reacting with an anti-OprI mab were selected. In-frame OprI-tagged proteins were detected and identified for six clones. The six C-tagged proteins were detected by immunoblot. The different mutants had insertions into a histone H1-like coding gene, cspD, encoding a cold-shock protein, dsbC, encoding a putative outer membrane lipoprotein involved in thiol-disulfide exchange, paaE, a ferredoxin-NADPH reductase gene, a gene for the catabolism of propionate, and one encoding an unknown protein.
