STRUCTURE of FULLY-CLEAVED GLYCINE-BOUND HUMAN L-ASPARAGINASE PROTEIN
Template:ABSTRACT PUBMED 23601642
Function
[ASGL1_HUMAN] Has both L-asparaginase and beta-aspartyl peptidase activity. May be involved in the production of L-aspartate, which can act as an excitatory neurotransmitter in some brain regions. Is highly active with L-Asp beta-methyl ester. Besides, has catalytic activity toward beta-aspartyl dipeptides and their methyl esters, including beta-L-Asp-L-Phe, beta-L-Asp-L-Phe methyl ester (aspartame), beta-L-Asp-L-Ala, beta-L-Asp-L-Leu and beta-L-Asp-L-Lys. Does not have aspartylglucosaminidase activity and is inactive toward GlcNAc-L-Asn. Likewise, has no activity toward glutamine.[1]
About this Structure
4osy is a 2 chain structure. This structure supersedes the now removed PDB entry 4hlp. Full crystallographic information is available from OCA.
