| 5. | In addition , it was also found that this protein shares limited but significant homology with the sam - dependent methyltransferase of mesorhizobium sp . bnc1 ( 32 % similarity ) , and the similarity of its 303 - 362 region to the 160 - 220 domains of l11 methyltransferases of e . coli ( prma ) is 41 % . it is suggested that methylation of l11 resulted in effects of noea on nodulation of 042bm
发现noea与中慢生根瘤菌( mesorhizobiumsp . ) bnc1可能的sam -依赖性的甲基转移酶相似性为32 ，而其303 - 362区域与大肠杆菌( escherichiacoli )的核糖体50s亚基的l11蛋白甲基转移酶( prma )的160 - 220结构域的相似性达到41 。 |
| 6. | A database search revealed that the putative sequence of the red gene shows 40 - 50 % identity with those of uroporphyrinogen iii methyltransferase ( encoded by coba gene ) from various kinds of bacteria . an over - expression of the coba gene in e . coli was reported to lead to an accumulation of trimethylated derivative of porphyrin termed trimethylpyrrocorphin and factor ii , which emit strong red fluorescence under uv
在ddbj中搜索到多种细菌来源的coba基因（编码uroporph仰nogenhmethyltransferase ）与redsene有40 50的同源性，并据报道，其中一个来源于pmpboibaclerilllaslldelll切chit的coba的基因，转人大肠杆菌、酵母菌及动物细胞后能使表达载体在紫外线下发射红色荧光。 |
