Attenuation The trp operon is also controlled by attenuation A leader sequence in the polycistronic mRNA upsteam of the coding region of the trpE structural gene encodes a 14 amino acid leader peptide including two tryptophan residues The RNA leader sequence can for several possible stem-loop secondary structures,one of which can act as a transcription terminator whilst a different stem-loop can act as an anti-terminator.

Results Mobiligy shifts of SSCP in exon 5 of presenilin-1 was detected in 4 cases with Alzheimer,s disease. Two missense mutation were found in the patients by DNA sequence analyse, one mutation was Leu 130 Met and the other was Vall 57 Leu.Another 11 patients showed one single strend shifted rapidly. But none mobility shifts of SSCP were found in patients with vascular dementia and normal controls. Conclusions It is shown that mutations in exon 5 of presenilin-1 also exist in the patients with sporadic Alzhemer?

结果 发现4名SAD患者的PCR产物SSCP分析发生泳动异常，DNA序列分析发现：这4名SAD患者的130号密码子发生了CTG→ATG错义突变(388位点发生C→A突变)，使编码的氨基酸由亮氨酸变为蛋氨酸(Leu 130 Met)；157号密码子发生了GTG→CTG错义突变(469位点发生G→C突变)，使编码的氨基酸由缬氨酸变为亮氨酸(Val 157 Leu)，另有11名患者SSCP表现为一条单链增快，其性质待定。
