DESCRIPTION

Also known as IAAA_ECOLI, iaaA, spt, ybiK. Degrades proteins damaged by L-isoaspartyl residue formation (also known as beta-Asp residues). Degrades L-isoaspartyl-containing di- and maybe also tripeptides. Also has L-asparaginase activity, although this may not be its principal function., May be involved in glutathione, and possibly other peptide, transport, although these results could also be due to polar effects of disruption. Heterotetramer of two alpha and two beta chains arranged as a dimer of alpha/beta heterodimers.
