Protein Family Models

This is a family of glycine cleavage T-proteins, part of the glycine cleavage multienzyme complex (GCV) found in bacteria and the mitochondria of eukaryotes. GCV catalyses the catabolism of glycine in eukaryotes. The T-protein is an aminomethyl transferase. [1]. 9047339.

YgfZ is a protein from Escherichia coli, homologous to the glycine cleavage system T protein, or aminomethyltransferase, GcvT (TIGR00528). Homologs of YgfZ other than members of the GcvT family share a well-conserved signature region that includes the motif, KGCYxGQE. Elsewhere, sequence diverge and length variation are substantial. Members of this family are mostly bacterial, largely absent from the Firmicutes and otherwise usually present. A few eukaryotic examples are found among the Apicomplexa, and a few archaeal sequences are found. Two functions implicated for this folate-binding protein are RNA modification (a function likely to be conserved) and replication initiation (a function likely to be highly variable). Many members of this family are, at the time of construction of this model, misnamed as the glycine cleavage system T protein.
