Protein attributes
| Sequence length | 746 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | This family of enzymes reversibly catalyzes the transfer of phosphate between ATP and various phosphogens (e.g. creatine phosphate). Ref.2 |
| Catalytic activity | ATP + taurocyamine = ADP + N-phosphotaurocyamine. Ref.2 |
| Cofactor | Magnesium. Ref.2 |
| Developmental stage | Expressed at low levels in 37-day sporocysts, increases 25-fold in the infective cercarial and early schistosomular stages. Levels decrease dramatically in adults, adult males have approximately twice the expression level as in adult females. Ref.1 |
| Sequence similarities | Belongs to the ATP:guanido phosphotransferase family. Contains 2 phosphagen kinase C-terminal domains. Contains 2 phosphagen kinase N-terminal domains. |
| Sequence caution | The sequence AAA29927.1 differs from that shown. Reason: Frameshift at positions 416, 434 and 644. The sequence CCD76533.1 differs from that shown. Reason: Erroneous gene model prediction. |
