Iridoid glucosyltransferase acting on genipin and 7-deoxyloganetin. No activity with 7-deoxyloganetic acid. Involved in geniposide biosynthesis. 7-deoxyloganetin + UDP-alpha-D-glucose = 7-deoxyloganin + H(+) + UDP kcat is 1.04 sec(-1) for genipin. kcat is 0.13 sec(-1) for 7-deoxyloganetin. kcat is 0.16 sec(-1) for UPD-glucose. Ubiquitous. Very low expression in stems. Up-regulated during the early stage of fruit ripening. Up-regulated by methyl jasmonate. Belongs to the UDP-glycosyltransferase family.
