>gnl|CDD|163497 TIGR03785, marine_sort_HK, proteobacterial dedicated sortase system histidine kinase. This histidine kinase protein is paired with an adjacent response regulator (TIGR03787) gene. It co-occurs with a variant sortase enzyme (TIGR03784), usually in the same gene neighborhood, in proteobacterial species most of which are marine, and with an LPXTG motif-containing sortase target conserved protein (TIGR03788). Sortases and LPXTG proteins are far more common in Gram-positive bacteria, where sortase systems mediate attachment to the cell wall or cross-linking of pilin structures. We give this predicted sensor histidine kinase the gene symbol psdS, for Proteobacterial Dedicated Sortase system Sensor histidine kinase. Length = 703
