Single particle cryo-EM of the P140-P110 heterodimer with an alternative conformation in the P140 stalk of Mycoplasma genitalium at a resolution of 3.7 Angstrom.
This entry represents the C-terminal domain from the Mycoplasma genitalium p110 adhesin protein. This domain has an Ig fold [1]. It is adjacent to the membrane. This domain contains a bound potassium ion [1].
This domain is found towards the C-terminal of adhesins from Mycoplasmas, such as adhesin P1, first identified as the major determinant for cytoadherence and gliding motility in M. pneumoniae. P1 forms a transmembrane adhesion complex with P40/P90, c ...
This domain is found towards the C-terminal of adhesins from Mycoplasmas, such as adhesin P1, first identified as the major determinant for cytoadherence and gliding motility in M. pneumoniae. P1 forms a transmembrane adhesion complex with P40/P90, called 'Nap', which mediates motility and infectivity in these organisms. The C-terminal domain is smaller than the large N-terminal domain and is mostly conserved [1,2]. It is followed by a transmembrane domain and acts as a stalk connecting the large N-terminal domain with the outer surface of the cell membranes [2,3]. P1 N-terminal domain is highly variable (Pfam:PF12378).
