RT biosynthesis in Methanococcus jannaschii.";
RL Biochemistry 42:9771-9778(2003).
CC -!- FUNCTION: Bifunctional enzyme that catalyzes the GTP-dependent
CC successive addition of two or more gamma-linked L-glutamates to the L-
CC lactyl phosphodiester of 7,8-didemethyl-8-hydroxy-5-deazariboflavin
CC (F420-0) to form polyglutamated F420 derivatives, and the FMNH2-
CC dependent reduction of dehydro-F420-0 to form F420-0. Is able to add up
CC to six glutamates to F420-0, producing F420-3 as the major product with
CC lesser amount of F420-4,5,6, consistent with it producing the
CC polyglutamated F420 compounds present in Mycobacterium smegmatis.
CC {ECO:0000269|PubMed:12911320}.
