Analysis of the Mitochondrial Genome in Hypomyces aurantius Reveals a Novel Twintron Complex in Fungi

Int J Mol Sci
PMCID: 4964425
PMID: 27376282
DOI: 10.3390/ijms17071049

[…] (the second intron of cox3) were predicted using the program INFERNAL [] by aligning with published group I introns [,,,]. Structure alignment data for most existing group I introns was available in GISSD (Group I intron structural alignment database) []. Key stem-loop structure elements were identified using the online program Mfold [], and final secondary structures were drawn using CorelDraw™ […]

[…] n the SS rRNA sequence of Aegyriana oliva were identified by the alignment of several intron-less cyrtophorian ciliates using CLUSTAL W 1.83 . The secondary structure of introns were predicted by the Group I Intron Sequence and Structure Database (GISSD) by using the covariance model (CM) of the seed alignment of IC1 and IE introns in the package INFERNAL V0.81 ( […]
