swrA

master activator of flagellar biosynthesis, modulator of [protein|D343D2096664A972026D911E7A17A35C7B1CD1C9|DegU] activity, converts [protein|D343D2096664A972026D911E7A17A35C7B1CD1C9|DegU]-P from a repressor to an activator of the fla-che operon, enhances [gene|7024E4162A6D827069F882FDEACA696EBC05DD40|sigD] transcription, controls the number of flagellar basal bodies, inactive pseudogene in strain 168
