title: A Myxococcus xanthus bacterial tyrosine kinase, BtkA, is required for the formation of mature spores.
abstract: A Myxococcus xanthus cytoplasmic bacterial tyrosine kinase, BtkA, showed phosphorylation activity in the presence of Exo. Phosphorylated BtkA was expressed late after starvation induction and early after glycerol induction. The btkA mutant was unable to complete maturation to heat- and sonication-resistant spores under both starvation- and glycerol-induced developmental conditions.
