Cryatal structure of ArnB K188A complexted with PLP and UDP-Ara4N
Template:ABSTRACT PUBMED 24460375
Function
[F5ZUF5_SALTU] Catalyzes the conversion of UDP-4-keto-arabinose (UDP-Ara4O) to UDP-4-amino-4-deoxy-L-arabinose (UDP-L-Ara4N). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides (By similarity).[HAMAP-Rule:MF_01167][SAAS:SAAS022850_004_033570]
