Which are highly conserved

Two ORFs, cphA and cphB, encoding proteins CphA and CphB with strong similarities to plant phytochromes and to the cyanobacterial phytochrome Cph1 of Synechocystis sp. PCC 6803 have been identified in the filamentous cyanobacterium Calothrix sp. PCC7601. While CphA carries a cysteine within a highly conserved amino-acid sequence motif, to which the chromophore phytochromobilin is covalently bound in plant phytochromes, in CphB this position is changed into a leucine.

Cold shock proteins (CSPs) form a family of highly conserved bacterial proteins capable of single-stranded nucleic acid binding. They are suggested to act as RNA chaperones during cold shock inhibiting the formation of RNA secondary structures, which are unfavourable for transcription and translation.

Cystinosis is a lysosomal storage disease caused by an accumulation of insoluble cystine in the lumen of the lysosome. CTNSencodes the lyso-somal cystine transporter, mutations in which manifest as a range of disorders and are the most common cause of inherited renal Fanconi syndrome. Cystinosin, theCTNSproduct, is highly conserved among mam-mals.

The description of globular protein structures as an ensem-ble of contiguous
closed loops or
tightened end fragments reveals fold elements crucial for the formation of stable structures and for navigating the very process of protein folding. These are the ends of the loops, which are spatially close to each other but are situated apart in the polypeptide chain by 25–30 residues. They also correlate with the loca-tions of highly conserved hydrophobic residues (referred to as topohydrophobic), in a structural alignment of the members of a protein family....

The conduction of protons through human Nox2 has pre-viously been shown to be dependent upon His115. Align-ment of sequences for both animal and plant Nox proteins indicated that histidines 115 and 119 are both highly con-served, while His111 was conserved among animal homo-logues of Nox1–4. To investigate the possible role that these histidine residues might play in the conduction of protons through Nox2, we have introduced both paired and single mutations into these histidine residues.

TheArabidopsisethylene-responsive element-binding factor (AtERF) fam-ily of transcription factors has 120 members, all of which possess a highly conserved ERF domain. AtERF1, AtERF4, AtEBP and CBF1 are members from different phylogenetic subgroups within the family.

DNA methylation affects important developmental processes in both plants and animals. The process of methylation of cytosines at C-5 is catalysed by DNA methyltransferases (MTases), which are highly conserved, both struc-turally and functionally, in eukaryotes. In this study, we identified and characterized cytosine DNA MTase genes that are activated with the onset of reproductive development in rice.
