From the original: (http://onlinelibrary.wiley.com/doi/10.1046/j.1365-2958.1998.00991.x/full)

Glucose is a sugar transported by the phosphotransferase system (PTS) and can enter the cell by either of two transporters: the glucose-specific EIIBC, product of the ptsG gene, located at 25 min on the E. coli chromosome; and the so-called mannose PTS, EIIAB, IIC, IID^Man encoded by the manXYZ genes (previously ptsML ) located at 41 min.

Since “41 min” also appears in the original, it is unlikely that these figures denote the orientation.

LZ is suggested to search with the key words “Glucose, min” (http://www.google.com.hk/#hl=zh-TW&source=hp&q=+%E2%80%9CGlucose%2C+min%E2%80%9D&btnG=Google+%E6%90%9C%E5%B0%8B&rlz=1R2ADRA_enHK408&oq=+%E2%80%9CGlucose%2C+min%E2%80%9D&aq=f&aqi=&aql=1&gs_sm=s&gs_upl=1771l1771l0l3265l1l1l0l0l0l0l495l495l4-1l1l0&bav=cf.osb&fp=c344195479ec8e10&biw=1280&bih=542

From http://www.horizon-scientific-press.co.uk/abs/abspts.html :

There are three main routes for the utilization of fructose by Escherichia coli. One (Route A) predominates in the growth of wild-type strains. It involves the functioning of the phosphoenolpyruvate:glycose phosphotransferase system (PTS) and a fructose operon, mapping at min. 48.7, containing genes for a membrane-spanning protein (fruA), a 1-phosphofructose kinase (fruK) and a diphosphoryl transfer protein (fruB), under negative regulation by a fruR gene mapping at min. 1.9.

Does “mapping at min. xxx” make sense ?

Would the “n” in “min” denote Nanomoles ?

If LZ has the answer, please tell us.
