Identification and Expression Analysis of an Atypical Alkaline Phosphatase in Emiliania huxleyi.

ABSTRACT: Emiliania huxleyi, a cosmopolitan coccolithophore in the modern ocean, plays an important role in the carbon cycle and local climate feedback as it can form extensive blooms, calcify, and produce dimethylsulfoniopropionate (DMSP) leading to the generation of dimethyl sulfide (DMS) which affects climate when oxidized in the atmosphere. It is known to be able to utilize dissolved organic phosphorus (DOP) by expressing a specific type of alkaline phosphatase (EHAP1) under phosphorus-limited conditions. In this study, we identified a new alkaline phosphatase (EH-PhoA^aty) in this species, which we found belongs to the newly classified PhoA^aty family. The expression of this atypical phosphatase was up-regulated under P-depleted conditions at both the transcriptional
