The blocks occurred in arrays whose relative order was absolutely conserved, confirming the existence of 'conserved modular arrays' in promoters.
However the sequence around the corresponding proline in human CrkII and CrkL (P237) is not well conserved, making the existence of such a regulatory mechanism less probable in human Crk [ 31].
It should be noted that, for all of the studied plants, homologues with existence conserved based pairs of length 3 6 amino acids were observed most often, and longer stretches were rarely observed.
Consequently, responses to the holiness problem sought to explain not only how God could remain holy despite having created a world such as ours, but also how he could remain holy despite conserving the world in existence and causally cooperating with all the events that occur in it.
Based on this observation and the existence of conserved LBD sequences, it is not unreasonable to hypothesize that many orphan receptors are ligand-dependent.
The preservation of the Env function as an entry mediator and limitations on size and expression impose restrictions on its variability and lead to the existence of conserved structures.
BLASTp and Pfam were used to scan the resulting sequences for the existence of conserved domains or similarity to non-serpentine receptor proteins [40], [41].
An interesting phenomenon in the evolution of whole genomes is the existence of conserved synteny, which is the maintenance of gene content and order in certain chromosomal regions of two or more related species.
Nevertheless, the existence of conserved OEP9 homologues in other diverse plant species (Figure 1c) and the absence of homologues in non-plant organisms, suggests that its function(s) is plant specific.
However, the RBHs exist between the N. limnia ammonium permeases and both N. maritimus and C. symbiosum A. The existence of conserved ammonium transporters in all three genomes suggests a necessary function for this activity.
