The organisation of the multigene family which encodes the major cell surface protein, pMGA, of Mycoplasma gallisepticum.

The genome of the avian pathogen Mycoplasma gallisepticum contains a number of related genes for putative adhesion molecules (pMGA). Cloning and sequence analysis of several pMGA genes suggested that all of them might be transcriptionally and translationally functional. Analysis of the gene sequence encoding the sole pMGA variant expressed in vitro in the S6 strain (pMGA1.
