2.A.7.14.6 Tobacco nicotine uptake permease 1, NUP1, of 353 aas and 10 TMSs. NUP1 transports tobacco alkaloids such as nicotine, but also efficiently takes up
pyridoxamine, pyridoxine and anatabine. The naturally
occurring (S)-isomer of nicotine was preferentially transported over the
(R)-isomer. NUP1, similar to PUP1 of A. thaiana,
transported various compounds containing a pyridine ring, but the
two transporters had distinct substrate preferences (Kato et al. 2015).
