Description

This track contains tRNA gene predictions by \ tRNAscan-SE v.1.23 by the Lowe lab.

A new covariance model is being used to detect non-canonically placed bulge-helix-bulge (BHB) introns (T.Lowe, in preparation) which are common in crenarchaeal species.

"Canonical" tRNA introns always occur two nucleotides 3' of the anticodon. When present, canonical introns are indicated by an "I" in the tRNA picture to the right. BHB introns can occur anywhere in the tRNA, and are completely removed before making secondary structure predictions (and pictures).
