Jw. Vrijbloed et al., A PLASMID FROM THE METHYLOTROPHIC ACTINOMYCETE AMYCOLATOPSIS-METHANOLICA CAPABLE OF SITE-SPECIFIC INTEGRATION, Journal of bacteriology, 176(22), 1994, pp. 7087-7090
Amycolatopsis methanolica contains a 13.3-kb plasmid (pMEA300) which i
s present both in the free state and integrated at a unique genomic lo
cation. A 2.1-kb pMEA300 DNA fragment was sequenced, revealing the put
ative attP site and two open reading frames, xis and int, showing simi
larity to genes encoding excisionases and integrases, respectively.
