title: Plant adenylate cyclases.
abstract: Adenylate cyclase (AC) (ATP diphosphate-lyase cyclizing; EC 4.6.1.1) is a key component of the adenylate cyclase signaling system and catalyzes the generation of cyclic adenosine monophosphate (cAMP) from ATP. This review summarizes data from the literature and the authors' laboratory on the investigation of plant transmembrane (tmAC) and soluble (sAC) adenylate cyclases, in comparison with some key characteristics of adenylate cyclases of animal cells. Plant sAC has been demonstrated to exhibit similarities with animal sAC with respect to certain characteristics. External factors, such as far-red and red light, temperature, exogenous phytohormones, as well as specific triggering compounds of fungal and bacterial origin exert a significant influence on the activity of plant tmAC and sAC.
