Abstract

Myxococcus xanthus has a large number of histidine kinase (HK) signal transduction proteins and many of these HKs are important for fruiting body development. Nla6S is an uncharacterized HK that lacks many of the conserved sequence motifs of typical HK proteins. In this study, we report that expression of the nla6S gene increases about sixfold during fruiting body development, that the Nla6S protein has the in vitro properties of HKs and that Nla6S is the prototype for a new family of HKs. To date, these Nla6-like HKs are found only in fruiting members of the Cystobacterineae suborder of the myxobacteria.
