Ancestral multipartite units in light-responsive plant promoters have structural features correlating with specific phototransduction pathways.
Regulation of plant gene transcription by light is mediated by multipartite cis-regulatory units. Previous attempts to identify structural features that are common to all light-responsive elements (LREs) have been unsuccessful. To address the question of what is needed to confer photoresponsiveness to a promoter, the upstream sequences from more than 110 light-regulated plant genes were analyze...
متن کاملPlant Metallothioneins: Putative Functions Identified by Promoter Analysis in Silico
Metallothioneins are low-molecular-weight proteins capable of covalently binding heavy metal ions due to the presence of many cysteine residues in their sequences. We analyzed the predicted amino acid sequences of 19 metallothionein (7 from Arabidopsis thaliana and 12 from Oryza sativa) and their promoter sequences in silico in order to determine the potential regulatory cis-elements present in...
متن کاملMetallothioneins: zinc, cadmium, mercury, and copper thiolates and selenolates mimicking protein active site features--structural aspects and biological implications.
Metallothioneins (MTs) define a superfamily of ubiquitous cysteine-rich low molecular weight proteins or polypeptides that contain polynuclear metalsulfur coordination sites formed by metal ions with d10 configuration. The most prominent characteristics of these biomolecules, which have been discovered as a cadmium and zinc containing protein in horse kidney by Margoshes and Vallee in 1957,1 ar...
متن کاملsignal specific successive approximation analog to digital converter
چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...
15 صفحه اولStructural Features of Toxic Chemicals for Specific Toxicity
We have studied the structural features of toxic chemicals from the RTECS database associated with specific toxicity. The frameworks, functional groups, and structure patterns of molecules are taken into account. Potential active frameworks, groups, and structure patterns for specific toxicity are gained by computational chemistry approaches. These structural features of toxic chemicals will be...
