Methanosarcina acetivorans

It has been suggested that an FeS flavoprotein with presumed electron transporting function may be involved in the reduction of the flavodiiron protein in Methanosarcina acetivorans (Saraiva et al. 2004). Since putative FeS flavoproteins with predicted hydrogenosomal target peptides have also...

Rigid cell walls are absent in some species, for instance in Methanosarcina frisia [62] and in Methanosarcina acetivorans [63], which exhibit only a proteinaceous S-layer outside the cytoplasmic membrane, although both species are closely related to other members of Methanosarcina on the basis of several metabolic and molecular characteristics.
