Gene Feature Overview

Strain Burkholderia cenocepacia J2315
Locus Tag
NCBI Locus TagQU43_RS46210
Replicon chromosome 1
Genomic location 2132827 - 2133774 (+ strand)
CommentIn PMID:27597847: arnT, arnB, arnC, arnA1, arnA2, and BCAL1935 located in the arn gene cluster harbored significantly low frequencies of transposon insertions (TraDIS). They were therefore categorized as essential by the authors.
