Skin element

The gene

Basic information

• Locus tag: BSU26310

Phenotypes of a mutant

• overexpression of YqaH causes cell filamentation and abnormal chromosome segregation, suggesting that overproduction of these proteins inhibits DNA replication, perhaps due to the interaction with DnaA PubMed
