Function of Mms6 related to biomineralization in Magnetospirillum magneticum AMB-1 with magnetosomes formation

Abstract:

Abstract: ［Objective］The function of Mms6 related to biomineralization on the magnetosome formation in Magnetospirillum magneticum AMB-1 was studied． ［Methods］ The transcript of mms6 was analyzed under static and aerobic conditions with Real-time RT-PCR．We observed the cell growth and magnetism of the mutation in which mms6 was mutated.［Results］The transcript of mms6 increased with the formation of magnetosomes．Mutation of mms6 caused about 50% decrease of magnetism in AMB-1 under static conditions，however，the cell growth of mutant was similar as to that of the wild type.［Conclusion］Gene mms6 is involved in the magnetosome formation of AMB-1.
