Both one- and two-dimensional peptide mapping techniques have been used to compare the 180-kilodalton subunits from maize chloroplast and type II nuclear DNA-dependent RNA polymerases (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6). Despite their similar molecular mass, these 180-kilodalton subunits are not the same. Also, two-dimensional tryptic maps of the 160-, 43-, and 28-kilodalton polypeptides from maize type II nuclear RNA polymerase and of the 140-, 42-, and 27-kilodalton polypeptides from maize chloroplast RNA polymerase show that each of these six polypeptides is unique.
一维和二维肽图谱技术均已用于比较玉米叶绿体和II型核DNA依赖性RNA聚合酶(核苷三磷酸:RNA核苷酸转移酶,EC 2.7.7.6)的180千道尔顿亚基。尽管它们的分子量相似,但这些180千道尔顿的亚基并不相同。此外,玉米II型核RNA聚合酶的160、43和28千道尔顿多肽以及玉米叶绿体RNA聚合酶的140、42和27千道尔顿多肽的二维胰蛋白酶图谱表明,这六种多肽中的每一种都是独特的。
