This study aimed to investigate for the first time, the profile ofPhysarummicroplasmodial phosphatase (PPH) activity toward the phosphorylated light chain ofPhysarummyosin II (PLCM) at pH 7.6, the velocity of cytoplasmic streaming, and PPH expression in spherule formation during dark starvation (DS). In this study, we cloned the full-length cDNA of PPH using polymerase chain reaction, based on the N-terminal amino acid sequence of the purified enzyme. The cDNA contained an open reading frame (ORF) of 1245 bp, corresponding to 415 amino acids. We confirmed that a rapid increase in PPH activity toward PLCM and a rapid decrease in cytoplasmic streaming velocity precede spherule formation byPhysarummicroplasmodia. The profiles of increase in PPH activity toward PLCM,PPHexpression, and PPH accumulation during DS were correlated with spherule formation in thePhysarummicroplasmodia. Moreover, application of the wheat germ cell-free expression system resulted in the successful production of recombinant PPH and in the expression of phosphatase activity toward PLCM. These results suggest that PPH is involved in the cessation of cytoplasmic streaming inPhysarummicroplasmodia during DS.
