Notes

[back to top]


The original sequence had a C-terminal frameshift extending YjjB, but homology analysis suggests that the extension is artifactual. No protein seen in minicells, but a LacZ fusion indicates this gene is expressed. Homology extends upstream to end of yjjP gene, but the predicted MW is a little higher than observed. A GTG alternate start at codon 3 has a better apparent RBS and would be coupled with the motif GTGA to the upstream gene stop codon. However the GTG start is not conserved in Salmonella and Yersinia, while the ATG start is conserved.[4]
