CC -!- FUNCTION: Cleaves the gamma-glutamyl peptide bond of glutathione and
CC glutathione-S-conjugate. Converts leukotriene C4 (LTC4), a glutathione-
CC S-conjugate, to leukotriene D4 (LTD4). Does not cleave gamma-glutamyl
CC compounds such as gamma-glutamyl leucine. May also catalyze a
CC transpeptidation reaction in addition to the hydrolysis reaction,
CC transferring the gamma-glutamyl moiety to an acceptor amino acid to
CC form a new gamma-glutamyl compound. Acts as a negative regulator of
CC geranylgeranyl glutathione bioactivity by cleaving off its gamma-
CC glutamyl group, playing a role in adaptive immune responses.

CC airway epithelial cells. Detected in brain, heart, kidney, liver, lung,
CC spleen, testis and trachea. {ECO:0000269|PubMed:9374738}.
CC -!- PTM: Cleaved by autocatalysis into a large and a small subunit.

CC -!- MISCELLANEOUS: A previous study reported that GSH and oxidized
CC glutathione (GSSG) are not substrates for murine GGT5 (By similarity).
CC However, this result contrasts with two studies reported that GSH is
CC indeed a substrate for GGT5 (By similarity).
CC {ECO:0000250|UniProtKB:P36269, ECO:0000250|UniProtKB:Q9Z2A9}.
CC -!- SIMILARITY: Belongs to the gamma-glutamyltransferase family.
