Abstract
Three genes hemE, hemF, hemG taking part in the porphyrin biosynthesis of Baccillus subtilis were mapped by two- and three-factor transduction crosses. The gene hemE determines uroporphyrinogen decarboxylase (EC 4.1.1.37) the gene hemF coproporphyrinogen oxidase (EC 1.3.3.3) and the gene hemG ferrochelatase (EC 4.99.1.1) enzymes. The loci hemE, hemF, hemG, are not linked to hemA locus and located near the argC and metD loci.
摘要
通过双因子和三因子转导杂交对参与枯草芽孢杆菌卟啉生物合成的三个基因hemE、hemF、hemG进行了定位。基因hemE决定尿卟啉原脱羧酶（EC 4.1.1.37），基因hemF决定粪卟啉原氧化酶（EC 1.3.3.3），基因hemG决定亚铁螯合酶（EC 4.99.1.1）。hemE、hemF、hemG位点不与hemA位点连锁，位于argC和metD位点附近。
