In addition, in Gram-positive Actinobacteria (Amycolatopsis methanolica, Mycobacterium gastri MB19) a methanol:NDMA (N,N -dimethyl-4-nitrosoaniline) oxidoreductase (MDO) has been reported (Bystrykh et al., 1993; Vanophem et al., 1993; Park et al., 2010). The gene mxaF encodes the catalytic subunit of PQQ MDH, which can be composed of two unique subunits (i.EC23 web e., MxaFI). Nonetheless, there is a distantly associated homolog in some methylotrophic Burkholderiales (Methylibium; i.e., the gene was named mdh2), which encodes an option PQQ-dependent MDH (Kalyuzhnaya et al., 2008). Beyond mdh2, a additional homolog of mxaF is recognized, i.e., xoxF, for which a functional function in methanolmetabolism is beneath debate. xoxF-like genes (synonymous to mxaF ) take place in Bradyrhizobiaceae along with other rhizobia, and may perhaps encode functional MDHs (Fitriyanto et al.Colcemid Cytoskeleton,Apoptosis,Cell Cycle/DNA Damage , 2011).PMID:23319057 Similar genes might be regularly detected in soil microbial communities using mxaF-specific primers (Table 1; Stacheter et al., 2013). If rhizobia that don’t possess the classical PQQ MDH (i.e., MxaFI; Moosvi et al., 2005), also make use of and develop on methanol has not systematically been analyzed yet. Nonetheless, Bradyrhizobium sp. MAFF211645 includes a Ce3+ -inducible XoxF-like MDH (Fitriyanto et al., 2011). The first functional proof of XoxF as a MDH was demonstrated inside the phototroph Rhodobacter sphaeroides (Wilson et al., 2008). Studies on Methylobacterium extorquens AM1 recommend that XoxF1 and XoxF2 are involved inside the regulation of mxaF (Schmidt et al., 2010; Skovran et al., 2011). Purified XoxF1 of Methylobacterium extorquens AM1 has highest methanol oxidation activities when cells were grown with methanol and 30 M La3+ . These activities had been comparable towards the canonical PQQ MDH MxaFI. The purified XoxF enzyme contained La3+ suggesting that XoxF is essential as a calcium-independent MDH that uses rare earth elements as cofactors (Nakagawa et al., 2012).
