Transcription unit       
Name: ftsK
Gene(s): ftsK   Genome Browser M3D Gene expression COLOMBOS
Promoter
Name: ftsKp2
+1: 932929
Sigma Factor: Sigma70 Sigmulon

                         -35                     -10        +1                   
Note(s): ftsKp2 is a nonessential promoter and it does not transcribe ftsK up to significant levels, except in the presence of ftsKp1 Dorazi R,2000

Note(s): ftsKp1 (dinH) is the main ftsK promoter during the cellular division process. Dorazi R,2000
Although a primer extension experiment has been done for this operon, the results indicated a region
(2-4 nucleotides) rather than a specific start site Dorazi R,2000 We have decided to place the transcription +1 site in the nucleotide closest to the -10 box.
