Phenotypes of a mutant
smooth colonies on MsGG medium, no [wiki|biofilm formation] in the absence of externally provided galactose [Pubmed|22893383,22113911]
the mutant is sensitive to exogenous galactose due to the accumulation of toxic UDP-galactose, this sensitivity can be suppressed by the inactivation of ''[gene|36930CC6FDFCA23D43E264FEA375B78A1434E1BD|galK]'' (no formation of the toxic UDP-galactose) or of ''[gene|5A6FBAE6553343092862CB79E150F934978C32A9|sinR]'' (constitutive expression of the ''[gene|F6C4634BF871D9A01E27014FFED7527C54BF560D|epsA]-[gene|9B668909E1380B287ACE58561DCF45FC29184D8B|epsB]-[gene|5DB168A3D087AAEB003D7548A1A4356ABD07F712|epsC]-[gene|223E979276F07D69D0DDAEE906023A8AB4F37F8E|epsD]-[gene|5D717F9F54693FD0AA8BC49E10348637858F88B9|epsE]-[gene|DB47BA2A5E3BED51DD8630E7D321C099D74B46CF|epsF]-[gene|C4D81976AAE888C4FE89A2EE5CF9A763CAD645FF|epsG]-[gene|BD843389F95BFB905071547AB243413A617F12A8|epsH]-[gene|6EBD8F7065B6C1996067F3120DD9CFEA91D3A444|epsI]-[gene|5272E807B6B98541EA155AA9748320E25767F096|epsJ]-[gene|66076952E512D53FC1FC62455A86ACFA21AE120D|epsK]-[gene|D67665412B78B56752B460219445E4BEF52C3A1A|epsL]-[gene|40EA584CF77FFF7D7E4E74B414EC69ADE3A1585B|epsM]-[gene|0D24AB8D446CFFBC6DEAD3C10D1FA59551545FE8|epsN]-[gene|52A47B49B1FB955EE7E3C316B57A2B4134F78480|epsO]'' results in detoxification of UDP-galactose) [Pubmed|22893383]
