Streptomyces ambofaciens e fa'apipi'iina le spiramycin antibiotic macrolide.O le fuifui gene biosynthetic mo spiramycin ua fa'ailoaina mo S. ambofaciens.I le faaopoopo atu i le gene regulatory srmR (srm22), na faailoa muamua (M. Geistlich et al., Mol. Microbiol. 6: 2019-2029, 1992), e tolu faʻatonuga faʻatonuga na faʻamaonia e ala i suʻesuʻega faʻasologa.O su'esu'ega o fa'amatalaga o le kenera ma su'esu'ega fa'aletino na fa'aalia e na'o le tasi o nei kenera e tolu, srm40, e tele sona sao i le fa'atonutonuina o le spiramycin biosynthesis.O le faʻalavelaveina o le srm22 poʻo le srm40 na faʻaumatia ai le gaosiga o le spiramycin ae o lo latou faʻaalia atili na faʻateleina le gaosiga o le spiramycin.Fa'amatalaga su'esu'ega na faia e ala i le fa'aliliuina-PCR (RT-PCR) mo genes uma o le fuifui i le vao-ituaiga galu ma i le srm22 (srmR) ma le srm40 fa'amalo mutants.O taunuʻuga mai le suʻesuʻega faʻamatalaga, faʻatasi ai ma mea mai suʻesuʻega faʻaopoopo, na faʻaalia ai e manaʻomia le Srm22 mo le faʻaaliga srm40, o le Srm40 o se auala faʻapitoa faʻamalosi e pulea le tele, pe a le o mea uma, o genes biosynthetic spiramycin.
