a phylogenetic analysis with the HOL gene suggests that the ability to produce methyl halides is widespread among vascular plants. All wild-type plants strongly favor the methylation of I- to Br- to Cl-. Adult plants show a relative methylation preference ratio for I:Br:Cl of roughly 10000:50:1. Juvenile plants showed a ratio of roughly 40000:9:1 |

AtHOL1 is involved in glucosinolate metabolism and defense against phytopathogens. CH3Cl synthesized by AtHOL1 could be considered a byproduct of NCS- metabolism |

bacteria contribute to iodine transfer from the terrestrial and marine ecosystems into the atmosphere |

marine microalgae are the main oceanic source of methyl bromide. The monohalomethanes produced by marine microalgae are probably important in the global cycling of gaseous organohalogen species, especially bromine and iodine |

marine microalgae are the main oceanic source of methyl bromide. The monohalomethanes produced by marine microalgae are probably important in the global cycling of gaseous organohalogen species, especially bromine and iodine. From the viewpoint of stratospheric ozone depletion, methyl bromide is the most destructive compound because it has a high ozone depletion potential |

the activation of AtHOL1, AtHOL2 and AtHOL3 genes contributes to the methyl halide emissions from Arabidopsis |

the enzyme may be involved in the detoxification of sulfur compounds produced by the degradation of glucosinolates to release them as volatile compounds. The volatile sulfur compounds, including CH3SH and CH3SCN and methyl halides, are believed to act as insecticidal or anti-pathogenic agents. Therefore, it is speculated that the enzyme plays a role in controlling the levels of anions that can inhibit metabolic enzymes in the leaves and also to protect them from damage caused by insects or pathogens |
| 2.1.1.165 | S-adenosyl-L-methionine + chloride |
an obvious function for a halophytic methylase would be the maintenance of homeostatic levels of cytoplasmic chloride ion. The secretion of excess chloride into the soil could not greatly benefit a halophytic plant. On the other hand, the synthesis and distillation of a volatile gas, methyl chloride, into the atmosphere could be a useful mechanism for disposing of excess chloride |
| 2.1.1.165 | S-adenosyl-L-methionine + chloride |
the enzyme is responsible for the massive amounts of CH3Cl produced by this fungus |
| 2.1.1.165 | S-adenosyl-L-methionine + chloride |
this enzyme possibly functions in the control and regulation of the internal concentration of chloride ions in halophytic plant cells |
