One is phosphatase - like domain and the other is glycerol - 3 - phosphate dehydrogenase domain . the former domain may catalog the dephosphation of the glycerol - 3 - phosphate and the later presumably synthesize the glycerol - 3 - phosphate according to similarity searching , domain localization and structure comparison . these should give an evidence for the functional research of this gene 通过相似性搜索，结构域定位以及结构比较分析我们认为磷酸化酶结构域很可能是催化3一磷酸甘油水解，而3一磷酸甘油脱氢酶结构域是催化3一磷酸甘油合成的，为这个基因功能的鉴定提供了根据
