The protein

Catalyzed reaction/ biological activity

• required for [SW|cell wall synthesis] during cell elongation [Pubmed|12896990]
• driver of [protein|A4C8719E06F774A6EB4D79757CC79CF89E453A54|MreB] dynamics [Pubmed|21636744,21636745]

[SW|Localization]

• extracellular (signal peptide) [Pubmed|18957862]
• localization depends on the availability of peptidoglyan precursors (lipid II) [Pubmed|23895585]
