CagA-Positive Helicobacter pylori Infection and Reduced Sperm Motility, Vitality, and Normal Morphology

Table 2

Linear homologies of different human enzymes with cag island protein of Helicobacter pylori J99 (taxId: 85963) (sequence ID: ref. NP_223194.1).

Enzyme	Expected value	Identity (%)	Positivity (%)	N. gaps (%)
Aldolase	0.4	78	77	0
Phosphoglycerate mutase	2.4	31	44	9
Pyruvate kinase	0.061	29	48	2
Succinate dehydrogenase	2.1	26	47	12

Expected value: significance of aligned amino acid sequences; identity %: percentage of identical amino acids in the two compared sequences; positivity %: percentage of amino acids that share the same behaviour from a chemical or an antigenic point of view; N. gaps %: number of intervals lacking linear homology between two homologue sequences.
