The deduced amino acid sequence is 77% identical to the gene from Citrus reticulata (GenBank,AF312229), and only 33% identical to the gene from Fragaria ananassa (GenBank AF000521), was suggested to encode a soluble acid invertase.

• 在GenBank中进行同源性检索的结果表明,该成员编码的氨基酸与植物可溶性酸性转化酶的氨基酸同源性较高,与宽皮柑橘(GenBank登记号AF312229)可溶性酸性转化酶基因编码的氨基酸具有77%25的同源性,而与定位于细胞壁的(不溶性)酸性转化酶同源性较低,最高仅33%25(Fagaria ananassa,GenBank AF000521)。
