Enzymatic depolymerization of emulsan.

abstract：:Replication-proficient (Rep+) revertants were isolated from mutants of IncFII plasmid NR1 that were replication defective (Rep-). The parental Rep- plasmids contained a mutation that inactivated promoter PE for transcription of RNA-E, a trans-acting repressor of translation of the essential RepA1 replication initiatio...
