Involved in the degradation of long-chain alkanes (PubMed:17372208, PubMed:22526792). Converts alkanes ranging from C(15) to C(36) into their corresponding primary alcohols (PubMed:17372208). a long-chain alkane + FMNH2 + O2 = a long chain fatty alcohol + FMN + H(+) + H2O kcat is 1.3 min(-1) with hexadecane as substrate. Optimum pH is 7.5. Optimum temperature is 60 degrees Celsius. Homodimer. 120-fold increase in transcription when crude oil is used as a sole carbon source instead of sucrose. Shows particular potential to be used for the treatment of environmental oil pollutions and in other biocatalytic processes (PubMed:17372208, PubMed:22526792). Random- and site-directed mutagenesis were used to generate mutants with increased activity toward hexadecane (PubMed:22526792). Belongs to the NtaA/SnaA/DszA monooxygenase family.
