Protein

Triosephosphate isomerase, glycosomal

Gene

N/A

Organism

Trypanosoma brucei brucei

Status

Reviewed-Annotation score: -Experimental evidence at protein levelⁱ

Functionⁱ

Miscellaneous

The enzyme contains a high proportion of positively-charged residues in beta-barrels V and VII (compared to the homologous regions in other triose isomerase sequences). Since 2 clusters of positive charges located at precise distances on the molecular surface are common to 4 glycosomal enzymes, it has been speculated that this might represent a signal for entry into glycosomes (PubMed:3015595).1 Publication
