Internal deletion

In this study, we examined a newly isolated Rb. spaeroides KD131 strain and a mutant derived from Rb. spaeroides KD131 by internal deletion of Hup SL and Phb C genes on their properties of growth and hydrogen evolution using different substrates and under different culture conditions. 

A purple non-sulfur bacterium, Rhodobacter sphaeroides KD131 was isolated from nature and its mutants, Hup and /or Phb were derived by internal deletion of Hup SL and Phb C.

Four 8 chain variants have been described in which deletions of amino acid residues are present (Table 6) these abnormal j3 chains are the product of a structural p chain gene with loss of one or more than one base triplet (internal deletion gene). 

High-level chloramphenicol-resistant strains of N. meningitidis serogroup B were isolated from 11 patients in Vietnam and one patient in France. Resistance was due to the presence of the catP gene on a truncated transposon that has lost mobility because of internal deletions (53). 

Neurexin-1, a trans-synaptic cell adhesion molecule that binds to neuroligins, has also been implicated in ASD (Szatmari et al., 2007 Feng et al., 2006). Briefly, large internal deletions in neurexin-1 coding exons were found in two affected siblings... 

Most yHCD proteins are now recognized to have internal deletions of variable sizes. Based on the location of the deletion, a classification was proposed , (Table 1.8 and Figure 1.18).
