1) Deletion of the C. glutamicum pmt gene (cg1014) which is involved in the transfer of mannose moiety, caused a complete loss of glycosylation of secreted proteins including the resuscitation-promoting factor 2 (Rpf2).
1) C. glutamicum gene cg1014 is conserved among actinobacteria including recently discovered Mycobacterium tuberculosis which encodes an integral membrane protein homologous to eukaryotic O -mannosyltransferases. 2) Pmt of C. glutamicum is the first representative from nonpathogenic Corynebacterineae family.
