Small subunits MttS and MttQ of the MttP transporter regulate trimethylamine transport in Methanosarcina mazei

The paper identifies MttS and MttQ as small proteins that regulate TMA transport via interaction with the MttP transporter in Methanosarcina mazei, revealing their role in TMA specificity and ecological adaptation.

H2 dependent modulation of Mtr activity by small protein MtrR in Methanosarcina mazei

The paper characterizes the small protein MtrR in Methanosarcina mazei, showing it modulates Mtr activity in response to hydrogen, affecting growth under varying H2 conditions.

Small protein mediates inhibition of ammonium transport in Methanosarcina mazei - an ancient mechanism?

This study identifies a small protein, sP36, that regulates ammonium transport in Methanosarcina mazei by interacting with AmtB1 and GlnK1, revealing an ancient archaeal mechanism distinct from bacterial regulation.
