Gene Feature Overview

Strain Burkholderia cenocepacia J2315
GCF_000009485.1|latest
Locus Tag
BCAL1929
NCBI Locus TagQU43_RS46190
Name
arnT
Replicon chromosome 1
Genomic location 2128443 - 2130119 (+ 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.
