Entry
EC 6.3.2.33                 Enzyme                                 
Name
tetrahydrosarcinapterin synthase;
H4MPT:alpha-L-glutamate ligase;
MJ0620;
MptN protein
Class
Ligases;
Forming carbon-nitrogen bonds;
Acid-D-amino-acid ligases (peptide synthases)
BRITE hierarchy
Sysname
tetrahydromethanopterin:alpha-L-glutamate ligase (ADP-forming)
Reaction(IUBMB)
ATP + tetrahydromethanopterin + L-glutamate = ADP + phosphate + 5,6,7,8-tetrahydrosarcinapterin [RN:R09594]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
tetrahydromethanopterin [CPD:C01217];
L-glutamate [CPD:C00025]
Product
ADP [CPD:C00008];
phosphate [CPD:C00009];
5,6,7,8-tetrahydrosarcinapterin [CPD:C18802]
Comment
This enzyme catalyses the biosynthesis of 5,6,7,8-tetrahydrosarcinapterin, a modified form of tetrahydromethanopterin found in the Methanosarcinales. It does not require K+, and does not discriminate between ATP and GTP [1].
