We added the locations of IS<i>1236</i> elements to the linked sequence. Otherwise it is the same as the one on NCBI. * [[https://www.ncbi.nlm.nih.gov/nuccore/NC_005966.1][Original sequence of the ADP1 type strain at NCBI (GenBank: NC_005966.1)]] * [[http://blast.ncbi.nlm.nih.gov/Blast.cgi?PAGE_TYPE=BlastSearch&USER_FORMAT_DEFAULTS=on&PAGE=MegaBlast&PROGRAM=blastn&GAPCOSTS=0%200&MATCH_SCORES=1,-2&BLAST_SPEC=MicrobialGenomes_62977&EQ_MENU=Acinetobacter%20sp.%20ADP1%20%28taxid%3A62977%29&DATABASE=Complete_Genomes&BLAST_PROGRAMS=megaBlast&MAX_NUM_SEQ=100&SHORT_QUERY_ADJUST=on&EXPECT=10&WORD_SIZE=28&TEMPLATE_TYPE=0&TEMPLATE_LENGTH=0&FILTER=L&FILTER=m&DB_GROUP=AllMG&SUBGROUP_NAME=All_genomes&DB_SUBGROUP=Complete_Genomes&SHOW_OVERVIEW=on&SHOW_LINKOUT=on&ALIGNMENT_VIEW=Pairwise&MASK_CHAR=2&MASK_COLOR=1&GET_SEQUENCE=on&NUM_OVERVIEW=100&DESCRIPTIONS=100&ALIGNMENTS=100&FORMAT_OBJECT=Alignment&FORMAT_TYPE=HTML&OLD_BLAST=false][BLAST a sequence against this genome at NCBI]] * [[https://github.com/barricklab/Abaylyi-EE/raw/master/reference/Acinetobacter-baylyi-ADP1-WT.gff3][ADP1 Barrick Lab strain (GFF3 Format)]] %BR% Incorporates a small number of mutations found in the ADP1 strain that the Barrick lab originally obtained from Valérie de Crécy-Lagard.

Most other common antibiotic selection markers can be used. We most commonly use kanamycin and spectinomycin resistance markers. The rate of spontaneous mutations to KanR is undetectable. SpecR mutants can arise at a low frequency (~10<sup>−8</sup> to 10<sup>−9</sup>) due to chromosomal mutations, so only use this marker for transformations that have a significantly higher frequency than this. | *Antibiotic* | *MIC* | *Standard Conc.* | *Status* | *Notes* | | Ampicillin (or carbenicillin) | 128 µg/ml | 100 µg/ml | %RED%Resistant%ENDCOLOR% | | | Kanamycin | 12.5-6.25 µg/ml (3.125µg/mL doesn't inhibit) | 50 µg/ml | Sensitive | MIC info from Barrick Lab results (G.S.) | | Spectinomycin | ? | 60 µg/ml | Sensitive | Spontaneous resistance | | Streptomycin | 6.25-12.5 µg/ml (escapes observed at 6.25µg/mL) | 25 µg/ml | Sensitive | Barrick Lab results (G.S.) | | Chloramphenicol | 4.0 µg/ml | 20 µg/ml | Sensitive | Spontaneous resistance | | Gentamycin | 1.3 µg/ml | 5 µg/ml | Sensitive | | | Tetracycline | 1.0 µg/ml | 10 µg/ml | Sensitive | | | Rifampicin | 0.6 µg/ml | 100 µg/ml | Sensitive | Spontaneous resistance | | Nalidixic acid (mutagen/causes DNA double strand breaks) | 1.9 µg/ml (no growth at 24 hr, but growth at 48 hr) (1 µg/ml doesn't inhibit) | 3.75 µg/ml | Sensitive | Barrick Lab results (G.S.) | *Source:* Gomez MJ, Neyfakh AA.

[[https://doi.org/10.1128/AAC.00579-06][DOI: 10.1128/AAC.00579-06]] ---++ Plasmids *Common high-copy number _E. coli_ plasmids do not work in ADP1.* A synthetic plasmid (pBAV1K) and broad-host-range plasmid (RSF1010) have been used successfully. In our hands, pBAV1K is less reliable. It is also important to note that because plasmid DNA is linearizes when taken up through the competence apparatus, that transformation of plasmids can be significantly less efficient than transformations used to incorporate DNA directly in the chromosome. | *Origin* | *Copy Number* | *Example* | | ColE1 (pUC, pBR322, etc.) type plasmids | %RED% Do not replicate %ENDCOLOR% | NA | | pBAV1K | Low-medium copy number | [[https://www.addgene.org/26702/][pBAV1K-T5-gfp]] | | RSF1010 | Low-medium copy number | [[https://www.addgene.org/110599/][pBTK403]] |
