Aside from the 16 toxin and 14 antitoxin genes identified in the R. felis chromosomal genome, we suggest that another ORF (RF1343) may encode a putative toxin with mild homology to the mazF toxin gene of several plasmid-containing bacteria.
CG10623 may encode a putative methionine synthase.
In the present study, a second gene (C05E11.6) which may encode another putative CHH family peptide was found in the C. elegans genome: this gene encodes a mature peptide of 97 amino acids containing six cysteyl residues whose positions are similar to those found in CHH family hormones.
This data could indicate that ythA and ypdK, which encode putative single transmembrane peptides, may play a role in regulation of membrane associated processes important for UV protection.
Since many eukaryotes encode putative enzymes of unknown function, they may also encode a cryptic MPD that would serve in an alternative biosynthetic route to IPP (1).
Two tRNAs were found to encode putative introns.
Strain 02161A, however, through sequence variation in this region, including a 117 bp deletion, possesses a 1,326 bp ORF which may encode a second putative mga-like regulatory gene, mgx2 (Fig. 3).
Comparative sequence analysis of the Mgx locus revealed only one significant variant, a strain with an insertion frameshift mutation in simA and a deletion mutation in a region downstream of mgx, generating an ORF which may encode a second putative mga-like gene, mgx2.
In both Aedes and Culex intron retention leads to a transcript that may encode a truncated, but functional, putative protein.
The results revealed the presence of at least eight putative genes, which may encode ten different laccases with peptide lengths ranging from 482 to 588 aa and molecular weights ranging from 53.5 to 64.4 kDa.
