Release of a cell surface protein during development of Myxococcus xanthus.
VGP is a major cell-surface glycoprotein present in vegetative cells of Myxococcus xanthus. Serological assays indicated that this protein was released from cells and accumulated in the medium during development, i.e., aggregation, fruiting body formation, and myxosporulation. Cells induced to form spores in the absence of aggregation retained VGP, indicating that loss of VGP was associated with developmental aggregation rather than myxosporulation. Anti-VGP antibodies inhibited vegetative cell gliding, suggesting the protein may also be required for motility.
