CC -!- FUNCTION: Core subunit of the mitochondrial membrane respiratory chain
CC NADH dehydrogenase (Complex I) which catalyzes electron transfer from
CC NADH through the respiratory chain, using ubiquinone as an electron
CC acceptor (PubMed:10852722, PubMed:18721790). Essential for the
CC catalytic activity of complex I (By similarity).

CC ECO:0000269|PubMed:18721790}.
CC -!- CATALYTIC ACTIVITY:

CC Note=Binds 1 [4Fe-4S] cluster. {ECO:0000305};
CC -!- SUBUNIT: Core subunit of respiratory chain NADH dehydrogenase (Complex
CC I) which is composed of 45 different subunits (PubMed:10852722,
CC PubMed:18721790, PubMed:25209663). This is a component of the iron-
CC sulfur (IP) fragment of the enzyme (PubMed:25209663).

CC ECO:0000269|PubMed:25209663}; Peripheral membrane protein
CC {ECO:0000305|PubMed:25209663}; Matrix side
CC {ECO:0000305|PubMed:25209663}.
CC -!- PTM: Hydroxylated ar Arg-114 by NDUFAF5 early in the pathway of
CC assembly of complex I, before the formation of the juncture between
CC peripheral and membrane arms. {ECO:0000250|UniProtKB:O75251}.
CC -!- SIMILARITY: Belongs to the complex I 20 kDa subunit family.
CC {ECO:0000305}.
