High impact information on merA

  • Northern blot and primer extension analyses identified two additional Hg(II)-inducible S. solfataricus genes, merH and merI (SSO2690), located on either side of merA [1].
  • Northern analysis of the merR mutant revealed merA transcription was constitutive and that transcript abundance was at maximum levels [2].
  • Primer extension analysis of merA mRNA predicted a noncanonical TATA box with nonstandard transcription start site spacing [2].
  • Northern analysis established that merA transcription responded to mercury challenge, since mRNA levels were transiently induced and, when normalized to 7S RNA, approximated values for other highly expressed transcripts [2].
