<p>The subunit composition of glycine cleavage system P-proteins have been classified into two types. Those from eukaryotes and some of the P-proteins from prokaryotes (e.g. <taxon tax_id="562">Escherichia coli</taxon>) are in the homodimeric form. The rest of those from prokaryotes are heterotetrameric, with two different subunits which, based on sequence similarities, correspond respectively to the N and C-terminal halves of the eukariotic-subunit [<cite idref="PUB00038183"/>].</p><p>This entry represents glycine dehydrogenase or glycine cleavage system P-protein subunit 1 (N-terminal subunit family).</p> Glycine cleavage system P protein, subunit 1, putative
