additional information | for maximal hydrolysis of glycosphingolipids by rhodococcal EGCases, a detergent such as Triton X-100 is required at a final concentration of 0.1-0.3% of the reaction mixture. The hydrolysis of water soluble gangliosides such as GM1 does not require the presence of a detergent. For the hydrolysis of GM1, the addition of 5% tetrahydrofuran instead of Triton X-100 increases the reaction rate of EGCase I by 2fold compared to that in the absence of a detergent. Tetrahydrofuran is ineffective in facilitating the hydrolysis of GbOse4Cer by EGCase I. DMSO, ethyl acetate, and methyl cellosolve are also not effective in stimulating the hydrolysis of GM1 or GbOse4Cer by EGCase I in the absence of a detergent | Rhodococcus sp. |

additional information | both rhodococcal EGCases I and II efficiently hydrolyze ganglio-series glycosphingolipids, whereas EGCase I hydrolyzes globo-series-glycosphingolipids much faster than EGCase II. The glycan chain from fucosyl-GM1 can be prepared by using EGCase I. EGCase III stands alone to hydrolyze 6-gala-series glycosphingolipids. All EGCases are not able to hydrolyze sphingomyelin and sulfatide | Rhodococcus sp. | ? | - |
