The revised sequence is further confirmed by comparing above FAB map with that of those peptides produced after further step of carboxypeptidase B digestion.
分别用羧肽酶B降解和部分胰蛋白酶酶解后的质谱数据进一步证实了以上的修正。
GS5 encodes a putative serine carboxypeptidase and functions as a positive regulator of grain size, such that higher expression of GS5 is correlated with larger grain size.
