克隆了肺炎克雷伯氏菌(Klebsiellapneumoniae)的glnB基因,该基因编码氮调节蛋白PII。该基因编码12429道尔顿多肽,与大肠杆菌glnB基因高度同源。还测定了引起谷氨酰胺营养缺陷型的glnB突变和Tn5诱导的Gln+抑制剂的序列。谷氨酰胺营养缺陷型被推断为PII的尿苷酰化位点的修饰的结果,并且抑制被证明是由GlnB中的Tn5插入引起的。在glnB的上游鉴定了未知功能的开放阅读框架的3′端,并且可能是含有glnB的操纵子的一部分。在已发表的豆科根瘤菌、慢生型大豆根瘤菌和巴西固氮菌谷氨酰胺合成酶结构基因(glnA)序列的上游,鉴定了与PII序列极其相似的glnB编码多肽的潜在同源物。
SummaryThe glnB gene of Klebsiella pneumoniae, which encodes the nitrogen regulation protein PII has been cloned and sequenced. The gene encodes a 12429 dalton polypeptide and is highly homologous to the Escherichia coli glnB gene. The sequences of a glnB mutation which causes glutamine auxotrophy and of a Tn5 induced Gln+ suppressor of this mutation were also determined. The glutamine auxotrophy was deduced to be the result of a modification of the uridylylation site of PII and the suppression was shown to be caused by Tn5 insertion in glnB. The 3′ end of an open reading frame of unknown function was identified upstream of glnB and may be part of an operon containing glnB. Potential homologues of glnB encoding polypeptides extremely similar in sequence to PII were identified upstream of published sequences of the glutamine synthetase structural gene (glnA) in Rhizobium leguminosarum, Bradyrhizobium japonicum and Azospirillum brasilense.
