Comment | B. subtilis contains two genes encoding glucosamine-6-phosphate deaminase enzymes, nagB and gamA. Only deletion of gamA significantly affects the ability of B. subtilis to grow on glucosamine or N-acetylglucosamine as the sole source of carbon |CITS: [23667565]|. Unlike the E. coli enzyme, B. subtilis NagB is monomeric and not allosterically regulated |CITS: [15755726]|. A crystal structure of NagB has been solved at 1.5 Å resolution |CITS: [15755726]|.

Highly expressed condition | (Etha) Cells were grown in a synthetic medium (J. Stülke, R. Hanschke, M. Hecker, J Gen Microbiol 139, 2041, Sep, 1993) with 0.2 % glucose as carbon source (Belitsky Minimal Medium/BMM) at 37 °C with vigorous shaking. Stress was applied to exponentially growing cultures at OD500nm of 0.4. Samples were harvested before stress [BMM]; after a rapid temperature up-shift from 37 °C to 48 °C [Heat]; after a temperature down-shift from 37 °C to 18 °C [Cold]. Ethanol stress was imposed by adding ethanol to a final concentration of 4 % (v/v) and cells were harvested 10 minutes after ethanol addition [Etha]. |
(G150) Purified spores were obtained by growing cells in DSM medium (P. Schaeffer, J. Millet, J. P. Aubert, Proc Natl Acad Sci U S A 54, 704, Sep, 1965) at 37°C for 48 hours after which they were washed ten times in ice cold distilled waterover a period of 5 days. Purified spores were heat activated at 70°C in Tris 10 mM pH8.4 and germination was initiated by the addition of L-alanine 10 mM (A. Moir, J Bacteriol 146, 1106, Jun, 1981). After incubation for one hour at 37°C, the culture was diluted with an equal volume of 2X LBmedium and germinating cells were harvested at 135, 150 or 180 minutes after addition of L-alanine [G135, G150 and G180]. | |
(LBGtran) Cells were grown in Luria-Bertani medium (Sigma) supplemented with glucose 0.3 % [LBG] at 37°C with vigorous shaking in flasks. Overnight cultures were diluted 2000-fold in fresh pre-warmed medium and samples were collected during the exponential [exp], transition [tran] and stationary [stat] phases of the growth cycle . | |

(M40t45) Cells were grown in LB medium at 37°C with vigorous shaking. An exponentially growing culture (O.D.600 approx. 0.25) was divided: one culture acted as the control [no mitomycin C , M0] while mitomycin was added to the second culture to a final concentration of 40 ng/ml [mitomycin, M40]. Samples were harvested at 0, 45 and 90 minutes after mitomycin addition [t0, t45 and t90]. | |

(T3.0H) Anon-sporulating B. subtilis strain was grown in a modified M9 medium in batch culture (T. Hardiman, K. Lemuth, M. A. Keller, M. Reuss, M. Siemann-Herzberg, J Biotechnol 132, 359, Dec 1, 2007). Glucose was exhausted when the culture reached an OD600 of approx. 10 and this was designated T0 [T0.0H]. 7 samples were harvested at various times before glucose exhaustion [T-5.40H to T-0.40H] and 10 samples at various times after glucose exhaustion [T0.30H to T5.0H]. | |

Siemann-Herzberg, J Biotechnol 132, 359, Dec 1, 2007). Glucose was exhausted when the culture reached an OD600 of approx. 10 and this was designated T0 [T0.0H]. 7 samples were harvested at various times before glucose exhaustion [T-5.40H to T-0.40H] and 10 samples at various times after glucose exhaustion [T0.30H to T5.0H]. | |

Lowely expressed condition | (C30) Cellsgrown overnight on LB agar plates at 30°Cwere harvested and used to inoculate pre-warmed minimal medium at OD600 of 0.5 (D. Dubnau, R. Davidoff-Abelson, J Mol Biol 56, 209, Mar 14, 1971). After growth at 37°C with vigorous shaking, cells were diluted ten times in fresh pre-warmed minimal medium and samples were harvested after a period of 30 minutes [C30] , i.e. before maximal induction of competence, and after a period of 90 minutes [C90], i.e. when competence induction was maximal. |
(LoTm) Cells were grown in Spizizen’s minimal medium (SMM) (C. Anagnostopoulos, J. Spizizen, J Bacteriol 81, 741, May, 1961) with vigorous agitation. The control culture was grown at 37 °C [SMMPr]. For growth at high or low temperatures, pre-cultures were grown at 37 °C, diluted to an OD578nm of 0.1 and subsequently transferred to 51 °C [HiTm] and 16 °C [LoTm], respectively. For the growth at high salinity, the salinity of the medium was adjusted by adding NaCl (5 M stock solution) to produce a final concentration of 1.2 M [HiOs]. | |
(Pyr) A 5 ml aliquot of LB medium was inoculated using frozen culture stocks. After a few hours growth at 37°C, precultures were prepared by inoculating 5 ml of M9 with this LB culture at several different dilutions usually ranging from 500- to 2000-fold. The dilution range was chosen so that one of these precultures had grown to and OD600 of 0.5 - 1.0 after overnight inculation. The chosen M9 medium precultures [at OD600 of 0.5 - 1.0] were used to inoculate 100 mL of M9 medium in 500 mL non-baffled shake flasks to an OD600 of 0.02. Filter-sterilized carbon sources were added separately to the medium M9 at following concentration: D-Glucose 3g/L[Glu], L-Malic acid 4.5g/L[Mal], L-Malic acid + D-Glucose 3 and 2g/L[M+G], D-Fructose 3g/L[Fru], D-Gluconate 4g/L[Glucon], Pyruvate 6g/L[Pyr], Glycerol 6g/L[Gly], Glutamic acid + Succinic acid 2 and 2g/L[G+S]. Where necessary, carbon source solutions were pH neutralized with 4 M NaOH prior to addition to the medium. Cells were harvested during the exponential growth phase. | |
(S3) Cells were grown in CH medium at 37°C and sporulation was induced by resuspension in warm sporulation medium as described by Sterlini and Mandelstam (J. M. Sterlini, J. Mandelstam, Biochem J 113, 29, Jun, 1969). The initiation of sporulation was designated T0, the time of resuspension. Samples were harvested at hourly intervals for 6 hours [S0 to S6] for the first set of experiments and for 8 hours [S0 to S8] for a second set of experiments. | |
