Element:CoDi6.5

Description

CoDi6.5 is a Ty1/Copia-like LTR retrotransposon described in the genome of the marine pinnate diatom Phaeodactylum tricornutum (Maumus et al. 2009; Bowler et al. 2008). We use the term CoDi-D (Llorens et al. 2009) to phylogenetically differentiate the two clades constituted by the distinct CoDi-6-like elements described by Maumus et al. (2009) in Phaeodactylum tricornutum and Thalassiosira pseudonana.

CoDi6.5 genome, of 5349 bp in size, includes LTRs of 348 nts flanking a single Open Reading Frame (ORF). The translated gag-pol polyprotein, of about 170 kD, presents the characteristic domain order of Ty1/Copia LTR retrotransposons: gag (displaying two zing-finger motifs), protease, integrase, reverse transcriptase and RNase H. For more details, see (Maumus et al. 2009).

Figure not to scale. If present, long terminal repeats (LTRs) have been highlighted in blue. Amino acid motifs noted with lines indicate the conserved residues in each protein domain, abbreviations below mean:

MA=matrix PR=protease DU or DUT=dUTPase TM=transmembrane TAV or IBMP=transactivator/viroplasmin or inclusion body matrix protein
CA=capsid RT=reverse transcriptase INT=Integrase CHR=chromodomain
NC=nucleocapsid RH=RNaseH SU=surface MOV=movement protein
PPT=polypurine tract PBS=primer binding site ATF=aphid transmission factor VAP=virion associated protein
